# Thread: Linearly Independent of exponenial functions

1. ## Linearly Independent of exponenial functions

The problem :

Show that the functions $\displaystyle e^{ax}$,$\displaystyle e^{bx}$ and $\displaystyle e^{cx}$ are linearly independent if $\displaystyle a \neq b \neq c$

Solution :
I calculated the wronskian, and my final answer is:

$\displaystyle e^{(a+b+c)x} \left( (b-a)c^2+(a-c)b^2+(c-b)a^2 \right)$

Clearly, $\displaystyle e^{(a+b+c)x} \neq 0$

The problem here is with $\displaystyle (b-a)c^2+(a-c)b^2+(c-b)a^2$

Since $\displaystyle a \neq b \neq c$, the following numbers can't be zero:
• b-a
• a-c
• c-b
Now, I stopped!

How I can prove that the expression $\displaystyle (b-a)c^2+(a-c)b^2+(c-b)a^2$ can't be zero so that wronskian will be non zero and hence the function are linearly independent?

2. [EDIT]: Your Wronskian is correct, just not simplified as much as it could be. If you simplify it a bit further, I think your result will pop right out.

3. I do not see any further simplification :S

4. Well, you're trying to set the expression equal to zero, and see under what conditions that can happen, right? So you have a quadratic in $\displaystyle a$, for example. Try solving

$\displaystyle (b-a)c^{2}+(a-c)b^{2}+(c-b)a^{2}=0$ for $\displaystyle a.$

What do you get?

5. it will be:

$\displaystyle (c-b)a^2+(b^2-c^2)a+(bc^2-cb^2)=0$

here:

$\displaystyle a'=c-b , b'=b^2-c^2 & c'=bc^2-cb^2$

so:

$\displaystyle a_{1,2}=\dfrac{-b' \pm \sqrt{ (b')^2 - 4a'c' } } { 2a' }$

it will be too long to solve it since i should find $\displaystyle (b')^2 , 4a'c'$ ... etc

Anyone could explain?

6. You should carry your computation through. It's not that much algebra. I think you'll find that your answers simplify down a great deal.

7. This is what I can do.
I do not see any further simplification.

8. Just plug in your primed variables. Try things. Note that $\displaystyle a^{2}-b^{2}=(a-b)(a+b).$

The simplification is, for me, about 5 lines' worth. If you're taking differential equations, you should definitely be prepared to do that much algebra.

This forum is about helping people get unstuck. It is not about giving people answers. So plug things in, show your work, and let me know if you get stuck.

9. xD.
yup yup it will be reduced to:

$\displaystyle a^2-(b+c)a+bc=0$

So the solution for this equation is:

$\displaystyle a_{1,2}=\dfrac{b+c \pm (b-c)}{2}$

so ?

10. Keep going. Take the plus sign solution: what is a? Take the negative sign solution: what is a?

11. The two solution are: b and c.
so?

12. So, you could factor the original expression

$\displaystyle (b-a)c^{2}+(a-c)b^{2}+(c-b)a^{2}$

as

$\displaystyle (a-c)(a-b)x,$

where $\displaystyle x$ is something or other. Do you think you could figure out what $\displaystyle x$ is? What do you want it to be?

13. Well,

$\displaystyle x=\dfrac{(b-a)c^{2}+(a-c)b^{2}+(c-b)a^{2}}{(a-c)(a-b)}$

I do not what I want it to be!

14. Consider the symmetry of the original expression. a, b, and c are all treated the same, right? You could probably replace a with b, b with c, and c with a without changing the expression (or maybe you'd get a minus sign - that's not important). But (a-c)(a-b) is not that symmetric. How could you make it equally symmetric? Another way of phrasing it is this: what is missing?

15. Sorry, but I did not understand "Consider the symmetry of the original expression".

## Detailed Solution

Concept:

Insulation resistance is inversely proportional to length of the cable

$$R = \frac{\rho }{{2\pi l}}\log \frac{{{r_2}}}{{{r_1}}}$$

$$\Rightarrow R \propto \frac{1}{l}$$

where,

r= radius of cable, r1 = radius of core conductor, l = length of cable

Calculation:

Given

l1 = 10 km, R1 = 1 MΩ, l2 = 50 km

$$\Rightarrow \frac{{{R_1}}}{{{R_2}}} = \frac{{{l_2}}}{{{l_1}}}$$

$$\Rightarrow \frac{{1 }}{{{R_2}}} = \frac{50}{10} \Rightarrow {R_2} = 0.2\;M{\rm{Ω }}$$

# Find the first two terms of the sequence for which Sn is given below Sn=n^2 (n+1)

more_vert

Find the first two terms of the sequence for which Sn is given below $$S_n=n^2 (n+1)$$

more_vert

verified

Solution ::
To find the first term

substitute n=1 in formula

$$S_1=1^2(1+1)=1(2)=2$$

To find the second term, substitute n = 2 in formula or equation

$$S_2=2^2(2+1)=4(3)=12$$

Now S2 is the sum of the first two terms.

the first term + the second term = 12

2 + the second term = 12

the second term = 12 - 2

the second term = 10

So, the first term = 2 and the second term = 10

#### Answer

$f(x)=x^4+10x^3+35x^2+50x+24$

#### Work Step by Step

RECALL: If $a$ is a zero of a polynomial, then $x−a$ is a factor of the polynomial. Thus, having $x=-1, -2, -3, -4$ as zeros of the polynomial function means that $x+1,x+2, x+3$, and $x+4$ are factors of the polynomial. Therefore the function is $f(x)=(x+1)(x+2)(x+3)(x+4) \\f(x)=x^4+10x^3+35x^2+50x+24.$

Talk Nonzero Temperature and Density

### Speaker

Dr Bjoern Wellegehausen (ITP University Giessen)

### Description

Theoretical knowlegde about the nonperturbative aspects of the phase diagram of QCD is of utmost importance for the design of future collider experiments or the understanding of cold and dense neutron stars. Since lattice QCD suffers from a severe sign problem at finite density, QCD-like theories are useful to understand the phase diagram of baryonic matter at finite density. Most QCD-like theories (two-color QCD, $G_2$-QCD or adjoint QCD) contain bosonic baryons, for example diquarks, or other more exotic types of matter. It is important to understand the interactions of these particles with ordinary fermionic baryons present in QCD. Simulations of these theories, for instance $G_2$-QCD, reveal an interesting and rich phase diagram at zero temperature. Many open questions arise, partly due to the lack of high precision or large volume/continuum data. This is the reason why we study two-dimensional QCD-like theories. In the talk we shall discuss differences between QCD-like theories at baryon chemical and isospin chemical potential. Furthermore we present simulation results on the phase diagram and spectroscopy at finite density for $G_2$- and two-color-QCD and compare it to free lattice fermions. Finally we give an outlook to our ongoing simulations in four dimensions.

## Strictly Triangular Matrices

If the entries on the diagonal of an upper (or lower) triangular matrix are all 0, the matrix is said to be strictly upper (or lower) triangular.
Example: The matrix
$\left| \begin{array}{ccc} 0 & 2 & 1 \\ 0 & 0 & 4 \\ 0 & 0 & 0 \end{array} \right|$
is strictly upper triangular and the matrix
$\left| \begin{array}{ccc} 0 & 0 & 0 \\ 2 & 0 & 0 \\ 3 & 0 & 0 \end{array} \right|$
is strictly lower triangular.

# What is the formula of bleaching powder?

What is the structure and preparation for bleaching powder? Why there is a controversy in the formula of bleaching powder?

I have encountered many forms of the formula of bleaching powder, like

1. $\ce{Ca(OCl)2}$ - wikipedia (it also mentions that bleaching powder is actually a mixture having other calcium compounds in it)
2. $\ce{Ca(OCl)Cl}$ - my textbook
3. $\ce{CaCl2 + Ca(OH)2 + H2O -> CaCl2\cdot Ca(OH)2\cdot H2O}$ - here the product is "apparently" bleaching powder.

My question is posed in other sites like:-

1. http://www.chemicalforums.com/index.php?topic=48844.0 - here it reads that the composition of bleaching powder has been disputed for decades.

2. http://chem-guide.blogspot.in/2010/04/preparation-properties-and-uses-of_6609.html - many forms of the formula are given here in this site although none of it has been proved right! Also can you explain about this Odling concept of bleaching powder mentioned in this site?

• Welcome to the site. Can you bring proofs of the bold version of controversy you're talking about? I even haven't seen the normal controversy about bleaching powder. – M.A.R. Jul 9 '15 at 8:48
• More importantly, are you asking about bleach powder for use in water sanitation and purification or are you asking about the hair product? – Ben Norris Jul 9 '15 at 10:44

The bleaching agent in all commonly available bleach powders is hypochlorite. Calcium hypochlorite is a pure compound with the formula $$\ce{Ca(OCl)2}$$ and is the active component in most bleach powders. (Note: active does not necessarily mean the most abundant component).

You presented three examples of formulations for bleaching powder that you have encountered:

1. $$\ce{Ca(OCl)2}$$
2. $$\ce{Ca(OCl)Cl}$$
3. $$\ce{CaCl2 + Ca(OH)2 + H2O -> CaCl2\cdot Ca(OH)2\cdot H2O}$$

The third species, $$\ce{CaCl2\cdot Ca(OH)2\cdot H2O}$$, cannot be a bleaching agent of any type because it does not contain hypochlorite. So I view that as plainly incorrect.

According to wikipedia,

Bleaching powder is made with slightly moist slaked lime. It is not a simple mixture of calcium hypochlorite, calcium chloride, and calcium hydroxide. Instead, it is a mixture consisting principally of calcium hypochlorite $$\ce{Ca(OCl)2}$$, dibasic calcium hypochlorite, $$\ce{Ca3(OCl)2(OH)4}$$, and dibasic calcium chloride, $$\ce{Ca3Cl2(OH)4}$$ [7].

I was able to find the source cited by Wikipedia online; it seems quite authoritative. It says:

Calcium hypochlorite solutions are made by suspending lime or hydrated lime in water and adding chlorine. However, reacting lime with water generates lots of heat, and this heat must be allowed to dissipate before chlorination. The maximum concentration is ∼85 g/L of available chlorine, above which dibasic calcium hypochlorite begins to precipitate. Chlorination can be done in a batch or continuous reactor similar to those used to make sodium hypochlorite, except that agitation is needed to maintain the suspension. In a batch reactor, agitation can be achieved using a mechanical stirrer, or, more effi ciently, by circulation. A centrifugal pump is used to pull the solution from the bottom of a conical tank and then reinject it tangentially to create a strong vortex. Alternatively, the solution passes through a packed tower before it returns to the tank. The packing in the tower creates shear that breaks the particles apart before the chlorine is injected at the bottom of the tower.57 The reaction is as follows: $$\ce{2Cl2 + 2Ca(OH)2 → Ca(OCl)2 + CaCl2 + 2H2O}$$

[...]

Hemibasic calcium hypochlorite, $$\ce{Ca(OCl)2\cdot 0.5Ca(OH)2}$$, can be precipitated from a solution of calcium hypochlorite at 40–80°C.143 These solutions are commercially made by chlorinating a slurry of hydrated lime.5 The precipitate is removed by filtration and dried. Although it may still be made in Asia, it has not been made in the United States or Germany since 1955.

[...]

Dibasic calcium hypochlorite, $$\ce{Ca(OCl)2 · 2Ca(OH)2}$$, is commonly used as an intermediate in making calcium hypochlorite, $$\ce{Ca(OCl)2}$$. It has never been successfully marketed as a product because it dissolves much too slowly.

[...]

Although calcium hypochlorite dihydrate, $$\ce{Ca(OCl)2 · 2H2O}$$, can be made by chlorinating a suspension of lime, it is difficult to filter, partly due to the presence of calcium chloride. Calcium chloride also reduces the stability of the dry product. [...] Sodium hypochlorite is commonly added to convert calcium chloride to calcium hypochlorite as follows: $$\ce{CaCl2 + 2NaOCl → Ca(OCl)2 + 2NaCl}$$

Pages and pages follow with detailed process descriptions for the manufacture of various formulations of bleaching powder. Suffice it to say, an ideal powder would be something like pure $$\ce{Ca(OCl)2 · 2H2O}$$, but this is very difficult to prepare economically, because of contamination with various amounts of chloride salts, hydroxide salts, or (depending on the route of manufacture) sodium salts.

• I have modified the question a little bit especially the 3rd reaction after realizing that I have wrote the reaction wrong. See if you can change your answer accordingly – Nilay Ghosh Feb 16 '16 at 12:35
• Hi Nilay, I don't want to edit my answer. I tried to answer the question you originally asked and feel that it is appropriate to leave that version of the question substantially in place. (Correcting typos or improving wording is fine, but changing the question content invalidates my answer.) Thus I rolled back your recent edits.

This 'void' means that your educational material is sub-standard.

You should so inform your teacher (you can cite the C++ standard §3.6.1/2 "It
shall have a return type of 'int'...").

Also the lack of anything named 'ByteVal' in the code, as referred to by the
question, indicates sub-standard teaching material.

This reminds me of the old joke: "There are 10 types of people - those
who understand binary and those who don't." That being said, here are
some base-neutral hints.

A number a_n ... a_1 a_0 in base b actually means:

\sum_{i=0}^n a_i b^i

Thus the decimal number 234 means:

2*(10^2) + 3*(10^1) + 4*(10^0)

Shifting a_n ... a_1 a_0 left by 1 yields:

a_n ... a_1 a_0 0

Or (if you prefer), a'_{n+1} a'_n ... a'_1 a'_0, where:

a'_{i+1} = a_i (for i >= 0)
a'_0 = 0

Thus, shifting 234 left by 1 in decimal yields:

2*(10^3) + 3*(10^2) + 4*(10^1) + 0*(10^0) = 2340

This is 10 times the original number. I wonder what would happen if you
did the same exercise in binary...?

Can you show me example how to shift left int 7 by four using this
technique? Because I have problems with that.

7 (base 10) = 4+2+1 (base 10) = 111 (base 2)

Shift left 4:

1110000 (base 2) = 64 + 32 + 16 (base 10) = 112 (base 10)

And don't grouch -- it's undignified I explained everything you
needed to know (besides just giving you the answer on a plate) in my

Pencil and paper? You multiply seven with ten and get seventy. Then
you multiply seven with six and get forty two. Then you add seventy
and forty two and get hundred twelve.

Alternatively, you fold the paper to make a paper aeroplane, draw cool
markings on the side of it with the pencil, and then multiply 7 by 16 in

Way too complicated: 6 times 20 is 120; subtract 8 and you have 112.

The easiest way is to memorize powers of two (and know how to calculate
the ones you don't have memorized), and then multiple (or divide, for
right shift) by corresponding power of two:

2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16

7 << 4 = 7*(2^4) = 7*(16) = 112

113 >> 4 = 113/(2^4) = 113/(16) = 7 remainder 1. Shifting drops
remainder, so just 7.

BTW, this works for unsigned integers only. If you are working with
signed data, the values and format will be different (twos complement vs
other representations may have different answers for the same problem).
One good way to handle those is to first convert to binary, and the
appropriate number of zeros, and convert back to decimal.

Huh? Everybody knows that a hexadecimal digit is 4 bits.
So left-shifting 0x7 by 4 bits makes it 0x70, which happens to be 112.

In addition to all the methods mentioned by the other responders, there
is another way which seems the most straightforward to me.

Double the number as many times as the shift value counts, in this case:

7 << 4 = 7 * 2 * 2 * 2 * 2 =
14 * 2 * 2 * 2 =
28 * 2 * 2 =
56 * 2 = 112

Replace "double" with "halve" for the right shift:

112 >> 4 = 112 / 2 / 2 / 2 / 2 =
56 / 2 / 2 / 2 =
28 / 2 / 2 =
14 / 2 = 7

If you get any decimal on the way simply discard it - for example:

113 >> 4

113, 56.5000, 28.2500, 14.1250, (7.0625 ==> 7)

or easier and faster:

113, (56.5 ==> 56), 28, 14, 7

[ digression

Here is some "Zen" method to calculate left shifts.

With one sheet of paper:
- ply it zig-zag 6 times (7-1) so that you get 7 "columns"
- open all the plies and flatten the sheet out again
- ply it in halves 4 times, following the perpendicular to the first
plies (that is, follow the "rows" direction, since the others were the
"columns").

Flattening out the sheet again and counting the "cells" will give the
result of the shift.

Plying a sheet of paper in halves more than three / four times, though,
can be a tough work, especially if the sheet is small and the paper is
heavy (thick).

-

With strings: take seven equally-long strings and tie them together with
a knot at half of their length, then group together the loose ends, add
another knot halfway through, regroup the endings and so on, four knots
in total.

Counting the "segments" (the strings going from knot to knot plus those
from the last knot to the loose ends) will give the result of the shift.

Also here, making a knot on a 56-strings "wire" can become a difficult
task, better to use long and thin strings.

-

Of course, the above methods can be improved by using multiplications
(rows * columns instead of counting cells, for example) but then it's
better to do this all by using just mathematics ;-)

By the way, I don't know any "Zen" way to calculate right shifts, can
anybody point out one?

Here is this week's POTW:

-----
Consider a strictly increasing sequence of natural numbers $(n_k)_{k = 1}^\infty$, and suppose $X$ is the subset of $[0,2\pi]$ consisting of all $x$ such that the sequence $(\sin(n_k x))_{k = 1}^\infty$ is convergent. Prove $X$ has Lebesgue measure zero.

Hi MHB community,

Due to illness, I'm posting a solution later than usual. No one answered this week's problem. You can read my solution below.

Let $f(x) = \lim_{k\to \infty} \sin(n_k x)$, for all $x\in X$. By the Riemann-Lebesgue lemma, $\int_X \cos(2n_k x)\, dx \to 0$ as $k \to \infty$. On the other hand, due to the identity $2\sin^2(n_k x) = 1 - \cos(2n_k x)$, the dominated convergence theorem gives $\int_X 2f(x)^2\, dx = \int_X 1\, dx$. Therefore, $f(x) = \pm \frac{\sqrt{2}}{2}$ for almost every $x\in X$. Again, by the Riemann-Lebesgue lemma and the dominated convergence theorem, $\int_X f(x)\, dx = 0$. Consequently, $m(X) = 0$.

Why is the aluminium boiling point higher than silicon? And why is silicon's melting point higher than aluminium?

Why is the Aluminium boiling point higher than silicon? And why is silicon's melting point higher than aluminium?

$$\ce{Si}$$ has 4 bonds which are covalent in nature. $$\ce{Al}$$ is metal thus possesses ionic bond.

Where have I not understood the concept?

• The concept itself does not seem to be awfully useful in predicting these differences. Oct 23 '20 at 6:07
• You can't directly compare the melting of aluminum with the melting of silicon. Silicon converts from a nonmrtallic structure to a metallic one when it melts, aluminum is metallic all the time. Oct 23 '20 at 9:34
• For one aluminium does not for ionic bonds with itself; those are metallic bonds.
– A.K.
Oct 23 '20 at 19:30
• BTW, though the BP of Al is 2743 K, it's vapor pressure is fairly high at lower temps... see en.wikipedia.org/wiki/Aluminium . Thus, Al metalization is easily done in vacuo perhaps 1,000 K cooler. So BP is not quite so sharp, in this case. Now gallium is ab bit more extreme... Oct 23 '20 at 20:14
• I'm afraid that the entire premise of the question is wrong. Both the melting point and the boiling point of Si are higher than than those of Al. Al: mp = 660 C, bp = 2519 C. Si: mp = 1414 C, bp = 2900 C. Oct 24 '20 at 4:14

1 Answer

Aluminium is a metal thus formed of metallic bonds. The positive Al cations are regularly arranged in a lattice and surrounded by a sea of free/delocalised negatively charged electrons (therefore metals can conduct electricity). The negative charge of electrons and positive charge of cations have strong attraction forces which require a lot of heat energy to break. However, silicon being a non-metal forms simple covalent bonds with other silicon particles. Covalent substances have weak intermolecular forces between their molecules so they require less energy. However, covalent atoms are hard to break from each other because the pairs of shared electrons are attracted to both positively charged nuclei.

• As u said covalent atoms are harder to break due to mutual sharing of electrons, the silicon would be expected to have a higher boiling point however it doesn't. Aluminium has a high boiling point, but a lower melting point than silicon. I guess this all can be imputed to their structures perhaps. Oct 26 '20 at 3:40
• Where this answer slightly misses: silicon has its diamond-like covalent structure only as a solid. Once melted it becomes metallic like aluminum, so a different comparison applies. Jul 18 '21 at 16:46

Pyramid (geometry)

(Redirected from Polyhedral pyramid)
Regular-based right pyramids
Conway polyhedron notation Yn
Schläfli symbol ( ) ∨ {n}
Faces n triangles,
1 n-gon
Edges 2n
Vertices n + 1
Symmetry group Cnv, [1,n], (*nn), order 2n

The 1-skeleton of pyramid is a wheel graph

In geometry, a pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a lateral face. It is a conic solid with polygonal base. A pyramid with an n-sided base has n + 1 vertices, n + 1 faces, and 2n edges. All pyramids are self-dual.

A right pyramid has its apex directly above the centroid of its base. Nonright pyramids are called oblique pyramids. A regular pyramid has a regular polygon base and is usually implied to be a right pyramid.[1][2]

When unspecified, a pyramid is usually assumed to be a regular square pyramid, like the physical pyramid structures. A triangle-based pyramid is more often called a tetrahedron.

Among oblique pyramids, like acute and obtuse triangles, a pyramid can be called acute if its apex is above the interior of the base and obtuse if its apex is above the exterior of the base. A right-angled pyramid has its apex above an edge or vertex of the base. In a tetrahedron these qualifiers change based on which face is considered the base.

Pyramids are a subclass of the prismatoids. Pyramids can be doubled into bipyramids by adding a second offset point on the other side of the base plane.

Right pyramids with a regular base

A right pyramid with a regular base has isosceles triangle sides, with symmetry is Cnv or [1,n], with order 2n. It can be given an extended Schläfli symbol ( ) ∨ {n}, representing a point, ( ), joined (orthogonally offset) to a regular polygon, {n}. A join operation creates a new edge between all pairs of vertices of the two joined figures.

The trigonal or triangular pyramid with all equilateral triangles faces becomes the regular tetrahedron, one of the Platonic solids. A lower symmetry case of the triangular pyramid is C3v, which has an equilateral triangle base, and 3 identical isosceles triangle sides. The square and pentagonal pyramids can also be composed of regular convex polygons, in which case they are Johnson solids.

If all edges of a square pyramid (or any convex polyhedron) are tangent to a sphere so that the average position of the tangential points are at the center of the sphere, then the pyramid is said to be canonical, and it forms half of a regular octahedron.

Pyramids with a hexagonal or higher base must be composed of isosceles triangles; a hexagonal pyramid with equilateral triangles would be a completely flat figure, and a heptagonal or higher would have the triangles not meet at all.

Right Star pyramids

Right pyramids with regular star polygon bases are called star pyramids.[3] For example, the pentagrammic pyramid has a pentagram base and 5 intersecting triangle sides.

Right pyramids with an irregular base

Example general right pyramid with apex above the centroid of a base polygon

A right pyramid can be named as ( )∨P, where ( ) is the apex point, ∨ is a join operator, and P is a base polygon.

An isosceles triangle right tetrahedron can be written as ( )∨[( )∨{ }] as the join of a point to an isosceles triangle base, as [( )∨( )]∨{ } or { }∨{ } as the join (orthogonal offsets) of two orthogonal segments, a digonal disphenoid, containing 4 isosceles triangle faces. It has C1v symmetry from two different base-apex orientations, and C2v in its full symmetry.

A rectangular right pyramid, written as ( )∨[{ }×{ }], and a rhombic pyramid, as ( )∨[{ }+{ }], both have symmetry C2v.

Volume

The volume of a pyramid (also any cone) is ${\displaystyle V={\tfrac {1}{3}}bh}$, where b is the area of the base and h the height from the base to the apex. This works for any polygon, regular or non-regular, and any location of the apex, provided that h is measured as the perpendicular distance from the plane containing the base. In 499 AD Aryabhata, a mathematician-astronomer from the classical age of Indian mathematics and Indian astronomy, used this method in the Aryabhatiya (section 2.6).

The formula can be formally proved using calculus. By similarity, the linear dimensions of a cross-section parallel to the base increase linearly from the apex to the base. The scaling factor (proportionality factor) is ${\displaystyle 1-{\tfrac {y}{h}}}$, or ${\displaystyle {\tfrac {h-y}{h}}}$, where h is the height and y is the perpendicular distance from the plane of the base to the cross-section. Since the area of any cross-section is proportional to the square of the shape's scaling factor, the area of a cross-section at height y is ${\displaystyle b{\tfrac {(h-y)^{2}}{h^{2}}}}$, or since both b and h are constants, ${\displaystyle {\tfrac {b}{h^{2}}}(h-y)^{2}}$. The volume is given by the integral

${\displaystyle {\frac {b}{h^{2}}}\int _{0}^{h}(h-y)^{2}\,dy={\frac {-b}{3h^{2}}}(h-y)^{3}{\bigg |}_{0}^{h}={\tfrac {1}{3}}bh.}$

The same equation, ${\displaystyle V={\tfrac {1}{3}}bh}$, also holds for cones with any base. This can be proven by an argument similar to the one above; see volume of a cone.

For example, the volume of a pyramid whose base is an n-sided regular polygon with side length s and whose height is h is

${\displaystyle V={\frac {n}{12}}hs^{2}\cot {\frac {\pi }{n}}.}$

The formula can also be derived exactly without calculus for pyramids with rectangular bases. Consider a unit cube. Draw lines from the center of the cube to each of the 8 vertices. This partitions the cube into 6 equal square pyramids of base area 1 and height 1/2. Each pyramid clearly has volume of 1/6. From this we deduce that pyramid volume = height × base area / 3.

Next, expand the cube uniformly in three directions by unequal amounts so that the resulting rectangular solid edges are a, b and c, with solid volume abc. Each of the 6 pyramids within are likewise expanded. And each pyramid has the same volume abc/6. Since pairs of pyramids have heights a/2, b/2 and c/2, we see that pyramid volume = height × base area / 3 again.

When the side triangles are equilateral, the formula for the volume is

${\displaystyle V={\frac {1}{12}}ns^{3}\cot \left({\frac {\pi }{n}}\right){\sqrt {1-{\frac {1}{4\sin ^{2}{\tfrac {\pi }{n}}}}}}.}$

This formula only applies for n = 2, 3, 4 and 5; and it also covers the case n = 6, for which the volume equals zero (i.e., the pyramid height is zero).[citation needed]

Surface area

The surface area of a pyramid is ${\displaystyle A=B+{\tfrac {PL}{2}}}$, where B is the base area, P is the base perimeter, and the slant height ${\displaystyle L={\sqrt {h^{2}+r^{2}}}}$, where h is the pyramid altitude and r is the inradius of the base.

n-dimensional pyramids

A 2-dimensional pyramid is a triangle, formed by a base edge connected to a noncolinear point called an apex.

A 4-dimensional pyramid is called a polyhedral pyramid, constructed by a polyhedron in a 3-space hyperplane of 4-space with another point off that hyperplane.

Higher-dimensional pyramids are constructed similarly.

The family of simplices represent pyramids in any dimension, increasing from triangle, tetrahedron, 5-cell, 5-simplex, etc. A n-dimensional simplex has the minimum n+1 vertices, with all pairs of vertices connected by edges, all triples of vertices defining faces, all quadruples of points defining tetrahedral cells, etc.

Polyhedral pyramid

In 4-dimensional geometry, a polyhedral pyramid is a 4-polytope constructed by a base polyhedron cell and an apex point. The lateral facets are pyramid cells, each constructed by one face of the base polyhedron and the apex. The vertices and edges of polyhedral pyramids form examples of apex graphs, graphs formed by adding one vertex (the apex) to a planar graph (the graph of the base).

The regular 5-cell (or 4-simplex) is an example of a tetrahedral pyramid. Uniform polyhedra with circumradii less than 1 can be make polyhedral pyramids with regular tetrahedral sides. A polyhedron with v vertices, e edges, and f faces can be the base on a polyhedral pyramid with v+1 vertices, e+v edges, f+e faces, and 1+f cells.

A 4D polyhedral pyramid with axial symmetry can be visualized in 3D with a Schlegel diagram—a 3D projection that places the apex at the center of the base polyhedron.

Any convex 4-polytope can be divided into polyhedral pyramids by adding an interior point and creating one pyramid from each facet to the center point. This can be useful for computing volumes.

The 4-dimensional volume of a polyhedral pyramid is 1/4 of the volume of the base polyhedron times its perpendicular height, compared to the area of a triangle being 1/2 the length of the base times the height and the volume of a pyramid being 1/3 the area of the base times the height.

# Which commutative groups are the group of units of some field?

Inspired by a recent question on the multiplicative group of fields. Necessary conditions include that there are at most $n$ solutions to $x^n = 1$ in such a group and that any finite subgroup is cyclic. Is this sufficient? (Edit: Well, no, it's not, since the only such groups which are finite are the cyclic groups of order one less than a prime power. Hmm.)

-
Regarding your edit: Yes, the finite case is known, so your question is about the infinite case, right? – Jonas Meyer Jan 26 '10 at 6:37
Perhaps not what you're looking for (and I do not really know their contents) but the following look interesting: jlms.oxfordjournals.org/cgi/pdf_extract/s2-1/1/369 and iop.org/EJ/abstract/0025-5726/35/2/A05 – Jonas Meyer Jan 26 '10 at 7:04
In the case of number fields or function fields for instance, units would mean the units in the ring of integers. – Anweshi Jan 26 '10 at 21:02
I don't think I've ever heard anyone use "units" in that way. – Qiaochu Yuan Jan 27 '10 at 3:27
A (closed) duplicate with further answers can be found here: mathoverflow.net/questions/204144/… – YCor Apr 30 '15 at 7:23

The following paper claims an answer to this question:

Dicker, R. M. A set of independent axioms for a field and a condition for a group to be the multiplicative group of a field. Proc. London Math. Soc. (3) 18 1968 114--124.

You can find it here:

http://math.uga.edu/~pete/Dicker1966.pdf

One might hope for a more aesthetically appealing characterization. I don't know if such a thing has ever been given.

-
Thanks! Maybe I should have just asked for nice necessary conditions... – Qiaochu Yuan Jan 26 '10 at 14:46
@qiaochu: I wonder why you are satisfied with this answer, because I already mentioned this paper in the other question which you refer to. – Martin Brandenburg Jan 27 '10 at 22:29
Oops; I don't seem to have read that question too closely. Sorry! – Qiaochu Yuan Feb 1 '10 at 4:07
Dear Pete: it seems that the link is broken. Do you still have the article? I would love to see it. – René Apr 28 '15 at 22:00

Another characterization is theorem 2.1 in this paper on the field with one element:

http://arxiv.org/pdf/0911.3537

If H is a commutative group, let H+ be H together with a new element 0. To give a field structure on H+ is equivalent to giving a bijection s:H+ --> H+ that commutes with all of its conjugates-by-H.

Maybe this is similar to Dicker's characterization? Dicker mentions the operation x --> 1-x, while the s in Connes-Consani is meant to be x --> x + 1.

## Abstract

It has been suggested that certain families of rudist bivalves (superfamily Hippuritoidea) were 'preadapted' to inhabit different environments and radiated to fill them. This scenario was based on a hypothesis of a geometric constraint of shell growth, a differential increase in the number of rudist genera possessing uncoiled shells relative to those possessing spirogyrate (i.e. coiled) shells, and a speculative phylogeny. In this paper, these ideas are reformulated and tested by comparing a postulated sequence of structural changes, expressed according to critical path method of management theory, and phylogeny, inferred from cladistic analysis. The hypothesis of constraint is unfalsified, and the cladogram is consistent with a proliferation of rudists possessing uncoiled shells. The proliferation may be attributed to the origin of an invaginated ligament, which should be considered as a direct adaptation.
