Dear

I want to draw the graphs of the attached system of PDEs for different values of M in 3D please fix my problem. I am waiting your positive response.

how I can  select 2D function (sigma) that these boundary conditions are satisfied?

thanks

sigma(1, z) = 0, sigma(r, 0) = 1, diff(sigma(0, z), r) = 0, diff(sigma(r, 1), z) = 0

Hi there,

I have the following complex-valued function,in polar coordinates:

Gamma is an arbitrary real constant.

How can a generate a 2D plot of w(z) using maple? 

Thanks!

Dearz 

I want to ask how to run multiple program at a time in maple? I am waiting your positive response. 

Hello,

I have a problem with graph using odeplot.

As showed in lower picture, the value of the y axis is so long.

So, i want to adjust the display digits to decrease the length of the values.

Do you have any method to do it?

Thank you!

I would like to check if op(n,g) exists for a given function g and a positive integer n.
How do I do it?
Naturally, I don't have the function g. It is theoretically created.
Thank you!

How do I solve a differential equation in Maple?"

Hello!

How can I make a list containing all inequalities
A[i,j] >=0 where A is a nxm-matrix?

This works, but si laborious:
[(A[i,1]>=0)$i=1..3,(A[i,2]>=0)$i=1..3,(A[i,3]>=0)$i=1..3];

works, but result is nested:
[[(A[i,j]>=0)$i=1..3]$j=1..3];

should work, but doesn't - why?
[((A[i,j]>=0)$i=1..3)$j=1..3];

Thanks in advance

Hi,

Not sure if I'm just being a bit daft but I'm struggling to obtain the correct solution to the following...

If we have the following:

And I enter the following into Maple:

Which I believe to be correct.  When I try to use p within the limit function, I cannot seem to get the answer 2 ?

What am I doing wrong here?  It's driving my bonkers!

Thankyou.

Hi,

I have an inverse I solved for with RootOf, which I transfrom and then try to numerically integrate the transformation. I get the following error: Error, (in convert/radical) too many levels of recursion

Integrating the inverse itself works, it is after applying the transformation 1/(1+x²) that I get the issue. Eventually I want to integrate something less simple, but here the problem already starts. 

Thanks for the help! Its for science!

Hey all together,

this is my first question in this community and it is maybe a very simple one:

If I have a given matrix. How can I process individual elements with an mathmatical operation?

For example, I have a diagonal matrix and want to get a matrix in which every non-zero element is the square root of the inverse of its former element.

Has someone an idea?

Thank you very much!

hello , there , i want ask a Question ,

i have a vector result n hier , and there is a long part with ^1/2 (like unter) , which is not defined before , just from compute ,i want to replace this part with A, and have tried to use subs , but it didnt work . 

And i have tried to define it before compute, and then use subs , aber it also didnt work .

so how can i replace or define this part in the result?

thanks

Dearz

I draw multiple graphs in singal coordinate with same line style. I don't know how to change the line style and color for g[1], g[2] and g[3] becuase of loop. Please some fix my problem to give them different style and color.

Hi all, 

Is there anyone who could solve this equaiton? I think there is no solution!!!!
