Entering 2-D Math

2-D math entry allows you to enter mathematical expressions in standard form as found in business and academic documents.
This document discusses general entry and entry for specific classes of expressions using 2-D math.

Standard Entry

Much of the standard entry is covered on the 2-D Math Shortcut Keys help page, including how to navigate 2-D expressions and how to escape characters that are shortcut keys. This page covers some further details and demonstrates a few nuances using examples that may be helpful.

2-D math input allows for implicit multiplication, that is, writing a multiplication operation without requiring a multiplication sign.

In general, you can use a space to imply multiplication.
The following examples use a space to imply multiplication.

 Using space to imply multiplication Expression and result Space between x and x $xx$ = ${{x}}^{{2}}$ Space between x and (x+1)   Space between f and x $\mathrm{expand}(\left(x+1\right)x)$ = ${{x}}^{{2}}{+}{x}$  $\mathrm{expand}\left(f\left(x+1\right)\right)$ = ${f}{}{x}{+}{f}$ No space between f and x The expression parses differently than $\mathrm{expand}\left(f\left(x+1\right)\right)$ = ${f}{}{x}{+}{f}$ $\mathrm{expand}\left(f\left(x+1\right)\right)$ = ${f}{(}{x}{+}{1}{)}$

Exceptions to this rule include cases where it is clear that only multiplication can be implied. Then a space is not necessary:

$\frac{2x}{2}$ = ${x}$

$\mathrm{expand}\left(\left(x+1\right)x\right)$ = ${{x}}^{{2}}{+}{x}$

Note: For a product containing integers and decimals, implicit multiplication can be used only if the number occurs in the left-most position in the product. For products of numbers, use explicit multiplication ($\mathbf{\cdot }$). However, products containing fractions can use implicit multiplication.

Valid

$2x$ = ${2}{}{x}$

Not valid

$23$

 Error, missing operation

Valid

$2\cdot 3$ = ${6}$

$2.3\cdot 5.3333333333$ = ${12.26666667}$

Valid

= $\frac{{10}}{{9}}$

With 2-D math input, multiple addition/subtraction operators and operations merge, unlike the situation with 1-D input:

$a++b$ = ${a}{+}{b}$

In addition, by default, expressions like $2\left(x\right)$ and $2.1667\left(y\right)$ parse to products instead of operators (the latter being the default in 1-D math).
This behavior can be changed using the Typesetting Rule Assistant, or by adjusting Typesetting settings as follows:

$\mathrm{Typesetting}:-\mathrm{Settings}\left(\mathrm{numberfunctions}=\mathrm{true}\right):$

$2\left(x\right)$ = ${2}$

$\mathrm{Typesetting}:-\mathrm{Settings}\left(\mathrm{numberfunctions}=\mathrm{false}\right):$

$2\left(x\right)$ = ${2}{}{x}$

2-D Operators

The 2-D math mode also allows direct entry of 2-D mathematical objects, such as integrals, sums, products, and limits. Note that these are also available on the Expression palette.

Command-Symbol Completion Keys

 • Command + Shift + Space, Macintosh
 • Ctrl + Space, Windows
 • Ctrl + Shift + Space, UNIX

Note: The following examples identify key strokes. The "Ctrl"+"=" key strokes can be substituted with pressing Enter.

As an example, you can enter a definite sum using the following keystrokes:

sum<command completion, and select the sum symbol><Ctrl+'>i=1<Right Arrow><Ctrl+">n<Right Arrow>i
<Ctrl+=>

$\sum _{i=1}^{n}i$ = $\frac{{1}}{{2}}{}{{(}{n}{+}{1}{)}}^{{2}}{-}\frac{{1}}{{2}}{}{n}{-}\frac{{1}}{{2}}$

A product can be entered in much the same way.

As for limits, the standard notation is also supported, including directional limits with the direction either inline or as a superscript. Here is an example with keystrokes:

lim<Ctrl+'>x->0+<Right Arrow>1/x<Right Arrow><Ctrl+=>

$\underset{x\to 0+}{\mathrm{lim}}\frac{1}{x}$ = ${\mathrm{∞}}$

And another example:

limit<Ctrl+'>x->0^-<Right Arrow><Right Arrow>1/x<Right Arrow><Ctrl+=>

$\underset{x\to {0}^{-}}{\mathrm{limit}}\frac{1}{x}$ = ${-}{\mathrm{∞}}$

Integrals require a special character for the 'd' prefix of the integration variable (DifferentialD), as shown in the following:

int<command completion and select the 'int' symbol>_0<Right Arrow>^10<Right Arrow>x d<command completion, and select 'd (differential)'>x<Ctrl+=>

${{\int }_{0}}^{10}xⅆx$ = ${50}$

Note: Integration limits can be entered over and under the integral sign if desired, as in the following:

int<command completion and select the 'int' symbol><Ctrl+'> 0< Right Arrow><Ctrl+">10<Right Arrow>x d<command completion and select 'd (differential)'>x<Ctrl+=>

$\stackrel{10}{\underset{0}{\int }}xⅆx$ = ${50}$

In addition, many formatted 2-D notations are directly available in the command-symbol completion mechanism.
For the int example above, an alternative entry technique is as follows:

int<command completion and select int with limits>0<tab>10<tab>x<tab>x<Ctrl+=>

${\int }_{0}^{10}xⅆx$ = ${50}$

Inert Functions
Inert versions of these functions are denoted by color. The inert versions of int, sum, and product have their symbol in dark gray, the inert version of eval has the evaluation bar in dark gray, and the inert diff function has the differentiation symbols in dark gray.

You can enter these functions in 2-D math in two ways:

1) Using command-symbol completion:

The inert functions can be entered with command-symbol completion using the inert versions of the function names, such as Int and Sum. For example:

Int<command completion and select the Int (inert) pattern with no limits>x<tab>x<Ctrl+=>

${\int }x{ⅆ}x$ = ${\int }{x}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}{ⅆ}{x}$

Note that inert operations are indicated by a trailing (inert) on the rule name.

In addition, inert versions of the operators themselves are also available as follows:

Int<command completion and select the "Int (inert)" symbol>x d<command completion and select "d (inert)">x<Ctrl+=>

= ${∫}{x}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}{ⅆ}{x}$

An entered integral can be converted to inert. Select the integral sign, and right-click (Control-click, for Macintosh) to display the context menu. Select 2-D Math>Convert To>Make Inert.

int<command completion enter>x d<command completion and select "d (differential)">x<highlight the integral sign and convert to inert><click after dx><Ctrl+=>

${\int }xⅆx$ = ${\int }{x}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}{ⅆ}{x}$

Separators while Programming in 2-D Math

In general, 2-D math statements do not need to be terminated with a semicolon. However, a statement separator (semicolon or colon) is necessary between two statements in one input region.  Otherwise, there will be ambiguity when Maple parses multiple statements.

In the following example, an error occurs because a separator has been omitted between the two statements entered between the use and end use keywords.

This issue can be resolved by adding a semicolon after the first statement.

 ${a}$ (3.1)

To suppress the output, use a colon after the end use statement:

Derivative Notation and Implied Dependency

Many standard derivative notations are supported for 2-D math entry methods, including prime notation, dot notation, Leibniz notation, and repeated index notation, but there are a number of settings that you must be aware of when using these.

Prime notation, by default, uses the variable x. When entering a derivative in prime notation, if no dependency is present, then the function is assumed to be a function of x. For example:

 Windows/UNIX Macintosh f''' f'''

$f'''$ = $\frac{{{ⅆ}}^{{3}}}{{ⅆ}{{x}}^{{3}}}{}{f}{}\left({x}\right)$

If an explicit dependency is present, then the function is assumed to be the derivative of a function of x evaluated at that value. If the dependent variable is not assigned, or is a known function (like sin), then D notation is used:

 Windows/UNIX Macintosh f'''(0) f'''(0)

$f'''\left(0\right)$ = ${{\mathrm{D}}}^{\left({3}\right)}{}\left({f}\right){}\left({0}\right)$

If the dependent variable is assigned, and is not a known function, then eval/diff notation is used:

 Windows/UNIX Macintosh q''(0) q''(0)

$q''\left(0\right)$ = $\genfrac{}{}{0}{}{\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{x}}^{{2}}}{}{q}{}\left({x}\right)}{\phantom{{x}{=}{0}}}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}{|}\phantom{\rule[-0.0ex]{0.1em}{0.0ex}}\genfrac{}{}{0}{}{\phantom{\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{x}}^{{2}}}{}{q}{}\left({x}\right)}}{{x}{=}{0}}$

The variable becomes more important when prime is applied to an expression, as follows:

 Windows/UNIX Macintosh (x^2+x)' (x^2+x)'

$\left({x}^{2}+x\right)'$ = ${2}{}{x}{+}{1}$

The variable to which prime corresponds can be changed in the Typesetting Rule Assistant, or using the command line Typesetting:-Settings command.
It has one special value, the empty identifier (blank or ), which indicates that prime notation corresponds to use of D or eval/diff notation:

$\mathrm{Typesetting}:-\mathrm{Settings}\left(\mathrm{prime}=\mathrm{}\right):$

$f''$ = ${{\mathrm{D}}}^{\left({2}\right)}{}\left({f}\right)$

$q''\left(0\right)$ = $\genfrac{}{}{0}{}{\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{\mathrm{_x}}}^{{2}}}{}{q}{}\left({\mathrm{_x}}\right)}{\phantom{{\mathrm{_x}}{=}{0}}}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}{|}\phantom{\rule[-0.0ex]{0.1em}{0.0ex}}\genfrac{}{}{0}{}{\phantom{\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{\mathrm{_x}}}^{{2}}}{}{q}{}\left({\mathrm{_x}}\right)}}{{\mathrm{_x}}{=}{0}}$

$\left({x}^{2}+x\right)'$ = ${2}{}{\mathrm{D}}{}\left({x}\right){}{x}{+}{\mathrm{D}}{}\left({x}\right)$

$\mathrm{Typesetting}:-\mathrm{Settings}\left(\mathrm{prime}=x\right):$

Note that the placeholder $\mathrm{_x}$ was used for eval/diff notation.

Dot notation, by default, uses the variable $t$, so names with a dot and no dependencies explicitly listed are assumed to depend on $t$:

 Windows/UNIX Macintosh f.. f..

$\stackrel{..}{f}$ = $\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{t}}^{{2}}}{}{f}{}\left({t}\right)$

Just as for primes, the use of dot with an explicit dependency different from the dot variable is assumed to be the derivative of a function of $t$ evaluated at that value:

 Windows/UNIX Macintosh f..(0) f..(0)

$\stackrel{..}{f}\left(0\right)$ = ${{\mathrm{D}}}^{\left({2}\right)}{}\left({f}\right){}\left({0}\right)$

Unlike prime, dot can only be used on function names.

The above are examples of implied dependencies, and when used, also provide a short form for entry of differential equations and conditions without requiring an explicit dependency:

$\mathrm{dsys}:=\left\{y''+y=0,y\left(0\right)=1,y'\left(0\right)=0\right\};$

 $\left\{{y}{}\left({0}\right){=}{1}{,}{\mathrm{D}}{}\left({y}\right){}\left({0}\right){=}{0}{,}\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{x}}^{{2}}}{}{y}{}\left({x}\right){+}{y}{}\left({x}\right){=}{0}\right\}$ (4.1)

Leibniz notation can be used to specify derivatives and partial derivatives, but short-form use for partial derivatives requires that the function dependencies be Suppressed. Function dependency suppression can be enabled in the interactive Typesetting Rule Assistant, or by using the Typesetting package Suppress command.

Univariate Examples:

 Windows/UNIX d/dx(x^2+x) Macintosh d/dx(x^2+x)

$\frac{ⅆ}{ⅆx}\left({x}^{2}+x\right)$ = ${2}{}{x}{+}{1}$

 Windows/UNIX d^2f/dx^2 Macintosh d^2f/dx^2

$\frac{{ⅆ}^{2}f}{ⅆ{x}^{2}}$ = $\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{x}}^{{2}}}{}{f}{}\left({x}\right)$

Short form and Multivariate Examples (require Suppress):

 Windows/UNIX Paf/Pax Macintosh Paf/Pax

$\frac{\partial f}{\partial x}$ = $\frac{{\partial }}{{\partial }{x}}{}{f}{}\left({x}{,}{y}\right)$

 Windows/UNIX Pa^4g/Pax^3/Paz Macintosh Pa^4g/Pax^3/Paz

$\frac{{\partial }^{4}g}{\partial {x}^{3}\partial z}$ = $\frac{{{\partial }}^{{4}}}{{\partial }{z}{}{\partial }{{x}}^{{3}}}{}{g}{}\left({x}{,}{y}{,}{z}\right)$

Note: Suppression also enables short-form entry of functions by name.

$f,g$ = ${f}{}\left({x}{,}{y}\right){,}{g}{}\left({x}{,}{y}{,}{z}\right)$

In addition, repeated index notation for partial derivatives can be used, if enabled.

$\mathrm{Typesetting}:-\mathrm{Settings}(\mathrm{userep}=\mathrm{true}):$

 Windows/UNIX Macintosh g_x,x,x,z g_x,x,x,z

${g}_{x,x,x,z}$ = $\frac{{{\partial }}^{{4}}}{{\partial }{z}{}{\partial }{{x}}^{{3}}}{}{g}{}\left({x}{,}{y}{,}{z}\right)$

 Vector Calculus In addition to standard matrix and vector-style entry, 2-D math also supports vector and vector calculus operations in standard syntax through the VectorCalculus package.   <1,2>.<0,1> $<1,2>.<0,1>$ = ${2}$  <1,2,0>times enter <0,1,0> $<1,2,0>×<0,1,0>$= ${0}{{e}}_{{x}}{+}{0}{{e}}_{{y}}{+}{{e}}_{{z}}$  Use of vector differential expressions with the nabla($\mathbf{\nabla }\mathbf{)}$ symbol is also supported, but coordinates must be explicitly set using VectorCalculus[SetCoordinates] before use.   $\mathrm{VectorCalculus}\left[\mathrm{SetCoordinates}\right]\left(\mathrm{cartesian}\left[x,y,z\right]\right):$  Gradient: nabla(x^2+y z) $\nabla \left({x}^{2}+yz\right)$ = ${2}{}{x}{\stackrel{{_}}{{e}}}_{{x}}{+}{(}{z}{)}{\stackrel{{_}}{{e}}}_{{y}}{+}{(}{y}{)}{\stackrel{{_}}{{e}}}_{{z}}$   Divergence: nabla. $\nabla . = ${1}$   Curl: nablatimes enter $\nabla × = ${0}{\stackrel{{_}}{{e}}}_{{x}}{-}{\stackrel{{_}}{{e}}}_{{y}}{+}{\stackrel{{_}}{{e}}}_{{z}}$   Laplacian: nabla^2(x^2+y z) ${\nabla }^{2}\left({x}^{2}+yz\right)$ = ${2}$   Other coordinate systems supported by VectorCalculus can be used as well.   $\mathrm{VectorCalculus}\left[\right]$

# Objectives

This page describes macros and functions related to linear and quadratic objective functions only, unless otherwise indicated. For nonlinear objective functions, see Nonlinear Modeling.

Use the @objective macro to set linear and quadratic objective functions in a JuMP model. The functions set_objective_sense and set_objective_function provide an equivalent lower-level interface.

To update a term in the objective function, see set_objective_coefficient.

To query the objective function from a model, see objective_sense, objective_function, and objective_function_type.

To query the optimal objective value or best known bound after a solve, see objective_value and objective_bound. These two functions apply to nonlinear objectives also. The optimal value of the dual objective can be obtained via dual_objective_value.

# Gray to Octal

Gray Code to Octal Converter is used to convert a Gray Code number into Octal format. Use the Gray Code Converter tool to convert between any number base and gray code.

#### Octal To Gray Code Converter

Convert Octal number to Gray Code

Background Information

### Gray Code

Gray Code also known as Reflected Binary Code is an ordering of binary numeral system used for error correction in digital terrestrial television and some cable TV systems.

### Octal

Octal number system is composed of digits from 0 to 7. It has a base of 8 hence the name Octal.

### Conversion from Gray Code to Octal

A Gray Code can be converted to Octal in three steps:-

1. Take the first bit of the gray code input and write it to the output
2. Repeat the following steps until you reach the end of the input
3. Take the second bit of the input and XOR it to the last bit of the output
4. Write this result to the output. So, 0 + 0 = 0, 0 + 1 = 1, 1 + 0 = 1 and 1 + 1 = 0.
5. Convert the binary output to octal

#### Example Gray Code to Octal Conversion

Let's say your Gray Code value is 11111011 and you want to convert it to it's Octal form.

1. Step 1: Take the first bit of the gray code input and write it to the output. Output is 1
2. Step 2: Repeat the steps below until you reach the end of the input
• Take the second bit of the input and XOR it to the last bit of the output. 1 + 1 = 0
• Write the result to the output. Output: 10
• Take the third bit of the input and XOR it to the last bit of the output. 1 + 0 = 1
• Write the result to the output. Output: 101
• Take the fourth bit of the input and XOR it to the last bit of the output. 1 + 1 = 0
• Write the result to the output. Output: 1010
• Take the fifth bit of the input and XOR it to the last bit of the output. 1 + 0 = 1
• Write the result to the output. Output: 10101
• Take the sixth bit of the input and XOR it to the last bit of the output. 0 + 1 = 1
• Write the result to the output. Output: 101011
• Take the seventh bit of the input and XOR it to the last bit of the output. 1 + 1 = 0
• Write the result to the output. Output: 1010110
• Take the eighth (last) bit of the input and XOR it to the last bit of the output. 1 + 0 = 1
• Write the result to the output. Output: 10101101
3. Step 3: So, our binary result is: 10101101
4. Step 4: Convert the binary output to octal. So, 10101101 becomes 255

# LaTeX embedded indexing

#### What is LaTeX?

LaTeX is a document preparation system that uses markup language. It is especially well-suited for technical documents that contain many special symbols, complex tables, and mathematical formulas. LaTeX originated from the TeX formatting system developed by Donald Knut, American mathematician and professor of Stanford University. The first version of this system was produced in 1978, and in the following years its algorithm was frequently modified and improved.

In 1983, an American computer scientist Leslie Lamport developed set of macros built on the top of TeX with many functionalities that can produce beautiful output of a document, or a book. The new system became known as LaTeX. There are few thousand of packages written over the years that can be used in LaTeX to accomplish typesetting-related tasks.

LaTeX approach is based on structure of the document, not on appearance. Changes in source code apply to the whole document, but in order to see the changes, you need to generate a PDF file. Fortunately, integrated PDF viewer is embedded in the most popular LaTeX editors, such as Texmaker, TeXstudio, LyX, and Overleaf. These programs are open source software, and they are distributed free of charge.

#### How to index in LaTeX?

Every LaTeX document begins with a preamble, where you can place a set of commands that affect the entire document. Here, you can determine settings of the layout, indicate paper size, fonts, margins, columns, etc. However, the functionality of the basic commands is limited. To enhance the capability of LaTeX, you may need to add special packages.

To enable indexing function in LaTeX, you need to install the makeindex package by adding the following line in the preamble: \usepackage{makeidx}. Index entries are created by placing \index codes in the layout of the document followed by a name or a subject in the curly brackets. For example: \index{main heading}.

Indexing feature in LaTeX is designed for ideal scenarios, where index, once generated, is required minimum or no revision. As every professional indexer knows, this is never the case. Multiple revisions, additions, deletions, merging entries and locators, breaking down locator strings are inevitable in every project. And this is where LaTeX fails profoundly. Editing index means finding entries in the text and making changes manually. This work could be time consuming and probably would not fit your client’s schedule.

I have developed my own approach to indexing LaTeX documents, which combines the use of the conventional indexing software (Cindex/Macrex/SKY), DEXembed macro, and LaTeX features. This method proved to be efficient regardless of the complexity of the layout.

Before we get onto how different data structures work, we need to briefly cover something called Big-Oh notation. Big-Oh notation is a neat way of describing how efficient algorithms are, by considering how algorithms perform for large sets of data. Whilst this is mostly a tutorial on data structures, not algorithms, we’ll still need it to cover the efficieny of the structures. This will not be mathematically rigorous, the aim is to just provide an understanding.

Consider for example a function that performs an action over a set of data, call it f(x), where x is the amount of data the function acts on. Let’s pretend that f(x) goes through a list of x numbers twice, and each time it checks if the number is even. If it is, it divides it by two. If it is odd, it adds one. It then outputs the first number in the sequence. Something like

A pointless function, I’m sure you’ll agree, but it will suit our purposes perfectly. We can see that f(x) needs to perform 2(2x) + 1 operations in total. Two for each x (checking if even and dividing or adding one), twice that for checking the list twice, then one extra for outputing the value. Simplifying we get 4x + 1 operations. We’ve assumed here that every operation takes the same amount of time, which is generally a safe bet for most operations (additions, division and so on), and we’ll ignore the fact that outputting takes an aeon in comparison. Let’s now consider what happens as x gets larger. The 4x term will easily swamp the constant + 1 at the end, so that won’t have much of an effect for large data sets. We can therefore ignore it. The 4 won’t have all that much of an effect (percentage wise) either. If x was 16 then the 4 would provide 25% of the multiplication, but if x was 1000 it would only provide 0.25%. We can therefore ignore it too, giving an approximate number of operations equal to x. We say that f(x) = O(x), or “f of x is Big-Oh of x”.

Now let’s consider a different function, one which calculates a list of sums in a very naive way

First we generate 100 square numbers so the algorithm has something to work with, then we get to the algorithm itself. The function adds up the first n square numbers and puts them in the nth position in the results array. If you’re disgusted by this function it’s a good sign, but let’s analyse it like we did to the first.

To calculate the sum of the first n squares the algorithm performs n additions and 2 assignments. Using the same logic as before, the n will be the important bit and not the 2, so we can ignore it. It does these sums 100 times, or more generally x times, but because n is changing the total number of operations will be 0 + 1 + 2 + 3 + ... + x. This sum is called an arithmetic series, and apologies if you’ve seen it before, if not then consider each part of this sum as a row with n balls on it

Clearly this is forming a triangle of height x and width x, so will have approximately x*x / 2 balls in total. Again the 2 is insignificant for large values of x, so we can ignore it and hence the total number of operations to calculate the sum of the first x square numbers (or any list of numbers for that matter) is approximately x^2. We therefore say that f(x) = O(x^2), or ‘f of x is Big-Oh of x squared’. Hopefully you can see that this algorithm will be slower for large data sets than the first!

If you were disgusted at the above algorithm then that’s good, because it was pretty terrible. After calculating the sum of the first 4 squares, say, we just need to add the fifth square number to calculate the sum of the first 5. The above algorithm can therefore be written to be O(x) instead! This is why we use this notation, to compare the efficieny of algorithms precisely instead of just saying ‘this one is obviously better’ and not having any data to back the statement up.

# Slicing a Square

Geometry Level 3

Consider a square with side length 1, whose interior is divided into three parts of equal area by two line segments.

If the sum of the slopes of these two line segments can be expressed as $$\dfrac AB$$, where $$A$$ and $$B$$ are coprime positive integers, determine $$A+B$$.
