> Hello Guys,

Please help me with this problem.

I generate the solutions to an equation and then I place them in a list as for example

> t1 := [((-4*Pi^2-beta^2+4*beta^2*Q^2*Pi^2+8*I*Pi^2*beta*Q)/(4*Pi^2+beta^2-4*beta^2*Q*Pi+4*beta^2*Q^2*Pi^2))^(1/2), -((-4*Pi^2-beta^2+4*beta^2*Q^2*Pi^2+8*I*Pi^2*beta*Q...

Hi , I'm Alan GHafur , I'm student in master dagree in Statistic in Irbil / Iraq .I want learn how can slove non linear function in Maple.

thank you for hlep me.

In 2D input it is possible to represnet

diff(f,x) as d/dx f

Is it possible to do

diff(f,x,x) as d^2/(dx)^2 f somehow?

Is it possible that we can add or modify new expressions in the palettes?

There are many ways to enter the second derivative in Maple.  Except for some silly reason I am stuck trying to figure out or find out how to enter it in 2d math form. 

d²    f
^---
dx²

Entering it like d^2 (right arrow) f  / (dx^2)  is not the right way to enter it.  What is the right way?

Okay, many questions here, maybe someone can answer one or two of them for me?  Can someone show a few simple multi-thread examples that work starting from version Maple 12 ?  Actually what version does multithreading actually really start working to improve calculation times? 

From what I understand the Threads package was introduced in Maple12 so it's almost experimental there.  An example I found using add() and Add() shows a slight...

Why is this software so unintuitive ?!

It can't even plot a vectorfunction, and when i finally found out (wich took a looong time because there is no help to get out there) i discovered my need for having to plot 2 functions in 1 graph wich is impossible !!

This is a ridiculous piece of software that i wouldn't even use, even if i got money for it !

I have fought to make this work because i had 3 small assignments to do, and thought they would be nice...

Can we assign a process to a portion of threads thereby limiting it's use on the cpu?  Or assign a processs that continually runs on a portion of the cpu while retaining the bulk processing power for other tasks other worksheets in Maple?

Fogive me here if I lack understanding:  As an example set aside say 1000 threads for the cpu and let one process run on one thread in the background essentially using only 0.1% processing power and leave the other 999...

I have two functions,

f(x) and its derivative...

how could i plot them together in a one single graph??? could you please help me???

Hello folks,

I have to admit I am somewhat new in using maple as well as in this board. However I used the search engine and could not find the answer to my question.

I coded a little program that - among other things - should randomly draw one entry from a set of integers. Thus I use the function choose from the RandomTools package. From other software packages (for example stata) I know that usually one would set a seed for those pseudo random numbers to be...

Can anyone explain the method that was followed in "Box Discretization" scheme in Maple Help?

Am trying to discretize 4th order terms in space..... d^h/dX^4 and third and second order in the same way....

I am computing eigenvalues of a 3X3 square Matrix that contains symbolic elements and many zeros. There are 2 zero eigenvalues and 1 non-zero. I'd like to request Maple to order the eigenvalues in a certain way, with the non-zero eigenvalue first. Oddly, the command LinearAlgebra:-Eigenvectors(A); orders them in a seemingly random way, with the non-zero eigenvalue either first or last, never in the middle. The LinearAlgebra:-Eigenvalues(A); commands seems...

Maple evaluates

> sum(1/z^2, z = 1 .. infinity)

to (1/6)*Pi^2. What do I do when sumation is over all even positive integers? Is there any  closed-form symbolic formula for this case?

Above is the minimal example. What I need is to compute 

> sum(2*binomial(m-1, k-1)*binomial(n-1, k-1)/binomial(m+n, m), k = 1 .. infinity)

where k belongs to a set of only even positive integers, not any posint. The second expression evaluates to 2*m*n/((m+n-1...

dsolve command doesn't work :(

it's very important =\

y*(dy/dx) + 2b*y*|y| + x*k^2 = 0

I'm new to Maple and am trying to solve a set of simultaneous equations. The equations have two independent variables x and T (contained within the letters "a" to "l" and "G" in code below) and 5 dependent varaibles X,Y,Z,W,V. Ultimately I want to solve for X...V with various values of x and T, but at the moment I'm struggling to get my code to work for just one x and one T value. The code I have so far is:

> solutions := solve({0 = -a*(h-Y-X-Z-V+W...
