To name actual numbers from the above table the digits are grouped into threes, each group of three is named, and separated with decreasing powers of a thousand. The groups are named by writing the first digit, if it exists, then hundred and then the name of the multiple of ten twenty followed by the last digit three. The separators should be replaced from right to left with increasing powers of a thousand, million, billion… For example $123,456,789$ becomes one hundred and twenty three million four hundred and fifty six thousand seven hundred and eighty nine. Due to the impractical length of numbers such as this it is uncommon to find numbers given to more than a few degrees of precision in this form, more often they are simply written using Arabic numerals. It should also be noted that if any of the groups is zero, then it is not stated, and an "and" is only included for terms less than one hundred. For example one million and one, and one million one thousand and five are both correct.

## General rules for very large numbers

Depending on whether you are using the old European system of powers of a million, or the more current system of powers of a thousand, then the name of a number can be created by extracting the name of the power from this table and then adding -illion to the end. This method should be treated with caution and it is common to find slight spelling variations, normally to aid with the pronunciation of the resulting word. In most situations it is preferable to write numbers such as these using standard form instead of words.[1]

Units Tens Hundreds
1 un deci centi
2 duo viginti ducenti
3 tre triginta trecenti
5 quinqua quinquaginta quingenti
6 sex sexaginta sescenti
7 septe septuaginta septigenti
8 octo octoginta octingenti
9 novem nonaginta nongenti

For an example of how this might work consider $10^{762}$. This can be written as $1000^{254}$ using the modern system. This is then interpreted as ducenti-quinquaginta-quattor-illion using the above table. The hyphens are normally removed leaving one ducentiquinquagintaquattorillion. In the older system it would be written as $1000000^{127}$ and interpreted as one centivigintiseptillion, noting that the e from septe has been ellided.

zlib-0.6.1.2: Compression and decompression in the gzip and zlib formats

Codec.Compression.GZip

Description

Compression and decompression of data streams in the gzip format.

The format is described in detail in RFC #1952: http://www.ietf.org/rfc/rfc1952.txt

# Documentation

This module provides pure functions for compressing and decompressing streams of data in the gzip format and represented by lazy ByteStrings. This makes it easy to use either in memory or with disk or network IO.

For example a simple gzip compression program is just:

import qualified Data.ByteString.Lazy as ByteString
import qualified Codec.Compression.GZip as GZip

main = ByteString.interact GZip.compress

Or you could lazily read in and decompress a .gz file using:

content <- fmap GZip.decompress (readFile file)

# Simple compression and decompression

Compress a stream of data into the gzip format.

This uses the default compression parameters. In partiular it uses the default compression level which favours a higher compression ratio over compression speed, though it does not use the maximum compression level.

Use compressWith to adjust the compression level or other compression parameters.

Decompress a stream of data in the gzip format.

There are a number of errors that can occur. In each case an exception will be thrown. The possible error conditions are:

• if the compressed stream is corrupted
• if the compressed stream ends permaturely

Note that the decompression is performed lazily. Errors in the data stream may not be detected until the end of the stream is demanded (since it is only at the end that the final checksum can be checked). If this is important to you, you must make sure to consume the whole decompressed stream before doing any IO action that depends on it.

# Extended api with control over compression parameters

Like compress but with the ability to specify various compression parameters. Typical usage:

compressWith defaultCompressParams { ... }

In particular you can set the compression level:

compressWith defaultCompressParams { compressLevel = BestCompression }

Like decompress but with the ability to specify various decompression parameters. Typical usage:

decompressWith defaultCompressParams { ... }

The full set of parameters for compression. The defaults are defaultCompressParams.

The compressBufferSize is the size of the first output buffer containing the compressed data. If you know an approximate upper bound on the size of the compressed data then setting this parameter can save memory. The default compression output buffer size is 16k. If your extimate is wrong it does not matter too much, the default buffer size will be used for the remaining chunks.

Constructors

 CompressParams

Instances

 Source # MethodsshowList :: [CompressParams] -> ShowS #

The default set of parameters for compression. This is typically used with the compressWith function with specific parameters overridden.

The full set of parameters for decompression. The defaults are defaultDecompressParams.

The decompressBufferSize is the size of the first output buffer, containing the uncompressed data. If you know an exact or approximate upper bound on the size of the decompressed data then setting this parameter can save memory. The default decompression output buffer size is 32k. If your extimate is wrong it does not matter too much, the default buffer size will be used for the remaining chunks.

One particular use case for setting the decompressBufferSize is if you know the exact size of the decompressed data and want to produce a strict ByteString. The compression and deccompression functions use lazy ByteStrings but if you set the decompressBufferSize correctly then you can generate a lazy ByteString with exactly one chunk, which can be converted to a strict ByteString in O(1) time using concat . toChunks.

Constructors

 DecompressParams Fields

 Source # MethodsshowList :: [DecompressParams] -> ShowS #

'Deflate' is the only method supported in this version of zlib. Indeed it is likely to be the only method that ever will be supported.

This specifies the size of the compression window. Larger values of this parameter result in better compression at the expense of higher memory usage.

The compression window size is the value of the the window bits raised to the power 2. The window bits must be in the range 8..15 which corresponds to compression window sizes of 256b to 32Kb. The default is 15 which is also the maximum size.

The total amount of memory used depends on the window bits and the MemoryLevel. See the MemoryLevel for the details.

Constructors

 WindowBits Int DefaultWindowBits Deprecated: Use defaultWindowBits. WindowBits constructors will be hidden in version 0.7

The default WindowBits is 15 which is also the maximum size.

A specific compression window size, specified in bits in the range 8..15

The MemoryLevel parameter specifies how much memory should be allocated for the internal compression state. It is a tradoff between memory usage, compression ratio and compression speed. Using more memory allows faster compression and a better compression ratio.

The total amount of memory used for compression depends on the WindowBits and the MemoryLevel. For decompression it depends only on the WindowBits. The totals are given by the functions:

compressTotal windowBits memLevel = 4 * 2^windowBits + 512 * 2^memLevel
decompressTotal windowBits = 2^windowBits

For example, for compression with the default windowBits = 15 and memLevel = 8 uses 256Kb. So for example a network server with 100 concurrent compressed streams would use 25Mb. The memory per stream can be halved (at the cost of somewhat degraded and slower compressionby) by reducing the windowBits and memLevel by one.

Decompression takes less memory, the default windowBits = 15 corresponds to just 32Kb.

Use minimum memory. This is slow and reduces the compression ratio. (Equivalent to memoryLevel 1)

Use maximum memory for optimal compression speed. (Equivalent to memoryLevel 9)

A specific level in the range 1..9

The strategy parameter is used to tune the compression algorithm.

The strategy parameter only affects the compression ratio but not the correctness of the compressed output even if it is not set appropriately.

Constructors

 DefaultStrategy Deprecated: Use defaultStrategy. CompressionStrategy constructors will be hidden in version 0.7 Filtered Deprecated: Use filteredStrategy. CompressionStrategy constructors will be hidden in version 0.7 HuffmanOnly Deprecated: Use huffmanOnlyStrategy. CompressionStrategy constructors will be hidden in version 0.7

Use this default compression strategy for normal data.

Use the filtered compression strategy for data produced by a filter (or predictor). Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of this strategy is to force more Huffman coding and less string matching; it is somewhat intermediate between defaultCompressionStrategy and huffmanOnlyCompressionStrategy.

Use the Huffman-only compression strategy to force Huffman encoding only (no string match).

Any nontrivial solution of (32.11.29) that satisfies (32.11.30) is asymptotic to $h{U}^{2}\left(-\nu-\frac{1}{2},\sqrt{2}x\right)$ as $x\to+\infty$, where $h$ $(\neq 0)$ is a constant. Conversely, for any $h$ $(\neq 0)$ there is a unique solution $w_{h}(x)$ of (32.11.29) that is asymptotic to $h{U}^{2}\left(-\nu-\frac{1}{2},\sqrt{2}x\right)$ as $x\to+\infty$. Here $U$ denotes the parabolic cylinder function (§12.2).

Now suppose $x\to-\infty$. If $0\leq h, where

Alternatively, if $\nu$ is not zero or a positive integer, then

 32.11.33 $w_{h}(x)=-\tfrac{2}{3}x+\tfrac{4}{3}d\sqrt{3}\sin\left(\phi(x)-\theta_{0}% \right)+O\left(x^{-1}\right),$ $x\to-\infty$,

where

 32.11.37 $\mu=1+\left(\ifrac{2ih\pi^{3/2}\exp\left(-i\pi\nu\right)}{\Gamma\left(-\nu% \right)}\right),$

and the branch of the $\operatorname{ph}$ function is immaterial.

Next if $h=h^{*}$, then

 32.11.38 $w_{h^{*}}(x)\sim-2x,$ $x\to-\infty$, ⓘ Symbols: $\sim$: asymptotic equality and $x$: real Permalink: http://dlmf.nist.gov/32.11.E38 Encodings: TeX, pMML, png See also: Annotations for §32.11(v), §32.11 and Ch.32

and $w_{h^{*}}(x)$ has no poles on the real axis.

Lastly if $h>h^{*}$, then $w_{h}(x)$ has a simple pole on the real axis, whose location is dependent on $h$.

For illustration see Figures 32.3.732.3.10. In terms of the parameter $k$ that is used in these figures $h=2^{3/2}k^{2}$.

# How To Add A Constraint In Maya

For example, if you want to quickly animate a sled sliding down a bumpy hill, you might first use a geometry constraint to constrain the sled to the surface. This adds a constraint to the selected bone. In Armature Pose Mode, Select one or more bones, and select last the bone that has the constraints you want to copy. Lectures cover the application of these tools in the VFX, game, and animation industries. technical solutions involving Maya’s motion paths and constraints and probably a dozen MELL scripts (OK, slight exaggeration). Add Joint1 to the Hypergraph (with Joint1 selected click Graph>Add Selected to Graph). When importing FBX files into the Unity Editor from Autodesk® Maya® and MotionBuilder®, you can include Constraints. C:\Program Files\Autodesk\Maya 2011 Subscription Advantage Pack\Python\lib\site-packages\maya\app\general\pointOnPolyConstraint. Baking out occlusion and diffuse maps will speed up your workflow while also adding more depth and realism to the textures. These different bodies will interact with each other by. Use the CopyObject method to copy the Dimension entity to a Block object. Step three - Go to edit>parent. constraint synonyms, constraint pronunciation, constraint translation, English dictionary definition of constraint. MEL to C++ or MEL to Python to C++ etc. Now save your textures that you have used for the mesh as a png/tga file 6. I also tried to manipulated controller by usin geo and joint. Add an IK Solver to lower_leg. The Parent Constraint Options window remains open. constraint let you constrain the position, orientation, or scale of an object to other objects. Autodesk App Store is a marketplace and a web service provided by Autodesk that makes it easy to find and acquire third-party plugin extensions, other companion applications, content and learning materials for Maya. Add a HumanIK > Character Add Constraints > HumanIK Add Legs Plant and connect it with the character and the full body plant to make the floor contact even more precise (the Legs Plant constraint only affects the characters legs (the hips won't move), taking into consideration the feet markers included in your characterization). I'll try to describe it: 1) First, open the cube's attribute editor. In character setup, the pole vectors of IK rotate plane handles for arm joint chains are often constrained to locators placed behind the character. The following graph shows Maya's budget constraint for coffee and croissants before the price change () and after the price change (). This is known as the. THE FIRST STEP IN TROUBLSHOOTING is to go to www. Here's what happens: The constraints now work like rigid wires, and lock all the rotation down. To tell it to do both you add a extra prim attribute to the polylines, @constraint_type, and set it to 'all'. Once you set a key on the child object, you will have a new attribute on the channel box called the “Blend Parent”. This will package all your animations into one file. With our control circles in the right spot, you can exapand the menu of the Nurbs circles and delete the Point Constraint from the circles. In animation, a restriction of the position, orientation, or scale of an object. Creating constraints can be as simple as selecting the objects you want to constrain with, selecting the object you want to constrain, and then selecting the appropriate constraint from the Constrain menu. sivakumar on September 23, 2019 12:05 PM. This class is a great start to our Animation and Character Programs. To adjust a constraint's attributes in the Attribute Editor, you must first select the constraint in the Outliner or the constraint icon in the workspace. We report a study of central Maya lowland dynastic information networks, i. Load the tcSoftIkSolver plug-in from the Maya plug-ins window. I've made a gun model wit ha skeletal rig - no hands, just the gun model. nCloth is a Maya toolkit that is used to simulate cloth and other dynamic surfaces for feature films and games. I didn't know what their difference are. There is no sound, so you'll need to watch the pop-up directions. …For example, the hinge of a door. If you need to add unique key constraints to a table after the fact, simply use the alter table command. I have a world link and the link constraint applied to the weapon but I can't get the arm to move to continue the animation. + Add current page to. The label's position is now defined or described by four constraints. …Window outliner. Maya has 3 jobs listed on their profile. For parent constraint, you can set key frames on the constraint. If the constraint to edit is ambiguous from the selection, then one will need to include the constraint node in the selection. View François Painchaud’s profile on LinkedIn, the world's largest professional community. So what ? There's already a Point constraint in the Maya toolset. The preset properties on the dynamicConstraint node determine the constraint's type (in this case, a Component to Component constraint) and how it behaves. Use hinge constraints to create effects such as a door on a hinge, a link connecting train cars, or the pendulum of a clock. Music is by Lino Rise - Channel Intro Hong Kong www. With nCloth dynamics, the hair is converted to a mesh which is simulated with nCloth and then converted back to hair. I wanted to animate the run cycle and since the gun is a rigid model as opposed to skin, instead of binding, I used Constraint. However, I am not sure if using a parent constraint in this instance is the right way to go about the procedure I'm performing. Thus, at one instance a field can hold int type data and at the next instance it may hold an array. This ensures the accuracy and reliability of the data in the table. To do this, in the Constraints panel under the Edit buttons click the Add Constraint button and choose IK Solver. 0 for Maya (maya script) $40. SERIOUS EFFECTS. Select hip_ ctrl and hip_joint and parent constraint it. ; Click Create Constraint or Apply. It works off of the current selection. This ensures the accuracy and reliability of the data in the table. To tell it to do both you add a extra prim attribute to the polylines, @constraint_type, and set it to 'all'. Modify parent constraint offsets Please send us your comment about this page Except where otherwise noted, this work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3. You can do this fast by selecting the target_bone first (copy of foot_bone), then the shin_bone and Ctrl+Shift+C then I. The Parent Constraint Options window remains open. The Maya Toolbelt by Michael McKinley A tutorial going over the Hinge Constraint in Maya 2016. I want to move a bone in my rig based on multiple inputs (each input is a float number). We will also see some examples of using constraints in typical production scenarios to understand the process better. The object should follow the hand joint around, and the constraint on the group means that you can still change translational, rotational, and scaling values on the objects inside the group. I cannot see it, but inserts show that the FK is present and operational. When you are finished with this course you will have the knowledge to direct all types of liquid and semi-solid simulations. They are about how to correctly place a polevector in maya in a way that when you create the polevector constraint your chain wont move , also it will be possible to offset the locator and so on. ) So from now on you and I might be see that the difference between rig in maya and rig in UE. What is the simplest way to remove a constraint from any constrained object? By this I don't mean physically deleting the controlling target or deleting that same target in the constrain rollout in the motion tab. MEL to C++ or MEL to Python to C++ etc. PARENTING AND CONSTRAINING IN MAYA ChildSphere_01 and middle-click-dragging it on top of ParentSphere_01. This could be done more rigorously with expressions but to quickly test an effect the look at constraint is a great technique. Click Create Constraint or Apply. mhtutorials. In the FX menu set, select nConstraint > Point to Surface >. Constraints can be column level or table level. Some great little tutorials showing off the basics of constraints in Maya, particularly for animation. Sure there is, but I'm out to show you that this point constraint has some neat advantages over its namesake. Software required: Maya. Use MathJax to format equations. Tutorial 11 - Maya Constraint - Duration: 14:21. If you're using Maya 2018 First try installing Maya 2018 Update 4 or 5. constraints) How to move a horizontal fixed-length line to two existing angled lines to form a triangle? This construction cannot be performed with just plain osnaps. 5 and input B=0. A flag is on a pole. mhtutorials. api as mapi import maya. Topic Options. Xcode is telling us that we haven't added any constraints yet. Part three will turn the bouncing ball into a character set. However, I am not sure if using a parent constraint in this instance is the right way to go about the procedure I'm performing. Also, Brads advice is dead on, Maya joints are fickle. The Maya Toolbelt by Michael McKinley A tutorial going over the Hinge Constraint in Maya 2016. Maya Training and Tutorials View all training Are you deleting the parent constraint? click the plus button next to the object. Constraint connects on both ends to pivot of the components. Select Constrain > Parent >. You can model, texture, light, animate, and render within the same environment. 1 enables users to set up procedural motion on animated skeletons at runtime. Maya matrix nodes – Part 3: Matrix rivet This post is a part of a three post series, where I implement popular rigging functionalities with just using maya’s native matrix nodes. A tutorial on basic poly modelling in Maya 2020. I wanted to animate the run cycle and since the gun is a rigid model as opposed to skin, instead of binding, I used Constraint. but I want whenever the first hand rotates, the other one move with it, so both hand hold their position on the gun. The ExoSwitch Constraint is by nature bi-directional, built to give the user the ability to determine "direction" on the fly. 0 for Maya (maya plugin) object can have multiple parents now Add the constraint with Constrain>Parent (the constraints menu is in the Animation Menu set -- or. pluralsight. However it doesn't seem to work with a joint. The nParticle object is now constrained to the target surface you selected, and both they are connected to the nParticle object's Maya. 0 for Maya (maya script)$20. Constraint logic programming lies at the intersection of logic programming, optimisation and artificial intelligence. Do you get nervous when you hear "constraint"? if yes, then you are in the right place, in this tutorial we will understand all the basics concept and usages of Maya's constraints Title Template. If you are an animator, you must have been in this position yourself. https://www. Software: Blender 2. The constraint data is indeed being saved when the FBX is exported out from Maya, we can see it if one reads the ascii itself. Any object can only take position information from one source. The Parent Constraint Options window closes. Constraints are used to limit the type of data that can go into a table. So what ? There's already a Point constraint in the Maya toolset. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. The tools costs $120 and a 30 day trial is available. Warning Could not find the bind pose. For example, if input A=0. finding a suitable travel partner) and structural constraints. constraint let you constrain the position, orientation, or scale of an object to other objects. Further, with constraints you can impose specific limits on objects and automate animation processes. Part 1: Node based matrix constraint. …And that's a way of limiting the movement of rigid bodies. If you have missed the first part, you can check it out here. Here is the VBA code for that. This is quickly done by selecting the start and end joints, and then the controller, and creating a point constraint (do not maintain offset). The character has two sets of arms as shown in the attached picture and what i needed to achieve was to be able to "Link" the rotations of the upper arm to the lower arm (and all joints under the hierarchy) so when the mocap animation runs, both arms would do the same thing. Note:You can set your Rigid Bodies to use Maya Fieldsfor greater control\s. Tools & Techniques Maya Project Overview If I need an object to be controlled by multiple inputs, I will simply add more constraints to the object and that is, in my eyes, what makes constraints so much more beneficial than simple parenting: you. If a constraint node is not selected it tries to guess at the desired one based on the selected components. Autodesk App Store is a marketplace and a web service provided by Autodesk that makes it easy to find and acquire third-party plugin extensions, other companion applications, content and learning materials for Maya. I want to iterate the constraints and query the targets for each of them:. " This will add the pin constraint to your scene and open its properties in the options window. With a huge passion for 3D and photogrammetry scanning we work passionately to bring new ideas and products to life for all CGI professionals with a frequent need to deliver lifelike visualizations under strict time constraints. pluralsight. See the complete profile on LinkedIn and discover Nataly’s connections and jobs at similar companies. Naturally… This doesn't work 🙂 I've tried literally everything I can think of. It's like the arm is stuck. When I first started learning Maya, I was very confused between parent and parent constraint. Position this directly out in front of the knee joint. Add Quantifiable Figures. If you need to add unique key constraints to a table after the fact, simply use the alter table command. You can do this fast by selecting the target_bone first (copy of foot_bone), then the shin_bone and Ctrl+Shift+C then I. Load the tcSoftIkSolver plug-in from the Maya plug-ins window.

Select Bullet> Active Rigid Body> to view the Active Rigid Body Options. The basic problem is that the SHOW CONSTRAINTS command doesn't show the constraints for geometry that clearly has them. The Inverse Kinematics constraint implements the inverse kinematics armature posing technique. So what exactly is rigging? Rigging is what makes deforming a character possible. Try adding numbers, percentages or any other quantifiable metric when writing a resume summary. This command is useful for editing and displaying constraint membership. To remove the problem of delivering a character into the pipeline in a pre-determined state, the constraint fully supports animating the drivers of the system. Main features: - Static, kinematic and dynamic rigid bodies (box, capsule, sphere, convex, custom and concave). If you keep your joints right you don’t have to do workarounds. ☑ Be able to confidently work with constraints for the rigging and animation processes in Autodesk Maya. Create a Dimension entity in model space. Now your leg is controlled with the target bone. …To add a force field constraint, you can select your cloth object, or vertices on…the object, and go up to that nConstraint menu, and choose Force Field. The label's position is now defined or described by four constraints. (e) either (c) or (b) depending on the constraint. This set of Maya animation tutorials, will guide you through the intuitive and fun animation tools of Maya. You can find the most up to date apps for Maya. In Maya, the camera has a camera shake attribute that will allow you to connect anything to it. Pan is modal: it stays active until you right-click or select another command. Select your Circle control, Shift Select your Joint, THEN add a Constraint. [Eric Luhta; Kenny Roy] -- Presents step-by-step walkthroughs covering the techniques of character animation with Maya 2012. In the quick tip video below, we’ll walk you through how you might constrain a nut along a bolt so that it screws and unscrews just like it. How to constraint a locator to a vertex it can be useful to rig a plane cloth using the smooth body and the locator to constraint a specific point to move it and have a good control of the dynamics. Since you've already keyfremed this IK handle it's taking it's position information from the animation curves you created. In this 3D animation tutorial in Autodesk Maya 2018 I will show you how you can let your character hold various objects such as rocks, swords etc using keyframe animation and locators with constraints. To do this, in the Constraints panel under the Edit buttons click the Add Constraint button and choose IK Solver. In the Parent Constraint Options window, set the constraint options you want. It talks about what the different constraints can do. With the face and the curve selected, I fired off the extrude tool. With just a few clicks, TSM2 installs a high-quality skeleton and proxy, adds a control rig, and applies basic but accurate skin weighting to human, animal, and creature models, a task that normally takes days. - Constraints. If you cannot add a constraint by selecting the constraint type, check the option box ( ) for that constraint to be sure the Add Targets option is selected. The Parent Constraint Options window closes. All constraints can be baked down to the skeletal animation using the 'transfer motion to skeleton' context menu found on constraints in the inspector. You are the one trying to create a polarizing view on me. Originally posted by Pure_Morning even easier is to create a camera and aim in the camera rollout. This adds a constraint to the selected bone. So I suggest you basic simple pipeline. I have a scene that i animated a long time, but later on made a major change in the rig, and the new rig no longer could work with this animation. The SimplyMaya Forums View all Forums A place you can ask or answer VFX related questions. Click the Animation tab of the Import Settings window and check Import Constraints: Import Settings with Import Constraints checked.

Working with constraints in Maya Learn how to become more adept at Technical Direction by understanding the world of constraints in Maya. Even though, Maya's UI is built entirely by Qt (PySide is a wrapper around Qt), the native elements are not usable with PySide functions. Sheryl Luzzadder-Beach, Timothy Beach, Samantha Krause. So, what we do is we try to import from PySide2 (Maya 2017) and if it cannot be found we do the imports from PySide (Maya 2016). ActiveDocument. In animation, a type of constraint that keeps an object aimed toward another object. Once the tcSoftIkSolver will be selected as "IK Solver" for an ikHandle, some attributes will be added to the same ikHandle:. So what ? There's already a Point constraint in the Maya toolset. Smooth mesh node (paid version) OS: Win64. This flag may be used together with other ones toggling some constraints on: if so, all constraints are disabled first (no matter the position of the -disable flag in the command line) then the specified ones are activated. Point (to only move), Orient (to only rotate), Scale (to only scale), Aim (for the joint to aim/rotate towards the control, wherever it is). AutoCAD Inventor :: How To Create A Motion Constraint Mar 14, 2012. There are also constraint methods that can be used to attach a jacket on top of the cloth, like the slide on surface constraint. Developing a flexible bone based facial rig that allows presets of facial expression but also allows an extra level or. Duplicate it and name it shoulder_ ctrl.

# distribution of random variable X

Random variable $X$ has exponential distribution $\varepsilon(\lambda)$ with the probability of $0.3$, and with the probability of $0.7$ it has a distribution whose density function is equal to $f_2(x)=1/2 e^{-|x+1|}$, for every $x \in R$. Find the density function and mathematical expectation of the random variable $X$.

I know what the exponential distribution looks like, but I just don't understand how to use any of the given information in order to solve the problem.. Any help would be really appreciated :)

• You can get the pdf by just adding the two pdfs multiplied by the corresponding weights. The expectation is then just an integral problem.
