I am trying to see if Maple can help me find a closed form for an infinite series. I do this:

restart:

s:=Sum(n^2/((Pi^2*n^2+beta^2*epsilon^2)*(exp(n))^4), n = 1 .. infinity);

value(s);

Maple returns with:

I'm making a student quiz and would like to use Maple to enter long division problems. Is there an expression template in the palettes for entering long division?

Thank you.

I would like to calcuate the residue of the following expression that I call res

>res:= subs([S1 = C3-sqrt(C3^2+4*C1*s), S2 = C3+sqrt(C3^2+4*C1*s)], exp(s*t)*(S1*(sinh((1/2)*S1)-cosh((1/2)*S1))*(sinh((1/2)*S2*eta)-cosh((1/2)*S2*eta))-S2*(sinh((1/2)*S2)-cosh((1/2)*S2))*(sinh((1/2)*S1*eta)-cosh((1/2...

Hi,

I need to model the MapleSim ground as a hard ground. For example when the robot swing leg hits the ground, it should not have negative vertical position. Basically, the robot will move on a surface.

Thanks...

Hello every one,

While plotting contours with grid size [200,200] my computer consume too much time to

execute the commond. To have an idea, the current process which I am running right now already

took 2380.22s and 68.60M and still its on.

Any suggestion to make the contour plot process faster?

Thanks

Hello,

This is more of a tutorial rather than a question because I found some mistakes and because the maple help file was a bit poorly explained and I am posting some additional details.

I am running version 16 of maple and version 7.12 R2011a of matlab.

If some of you are wondering how to call a Matlab user function in Maple this is what I have done:

First of all in the maple...

When I export my plot to PDF, adobe acrobat says: A drawing error occurred. Other programs see my PDF as corrupt. I would use a .eps file, but my plot has a semi-transparent component that doesnt show up very well as an eps. Any ideas?

Thanks

I recently purchased a new MacBook Pro (retina) with Mountain Lion and found that my Maple 12 programs would not run.  So I updated to Maple 16.  Initially all seemed to work well.  But now when i try to open a Maple .mw file, I get the message

"File acm23test.mw could not be found.  Please select a different file."

What has happened and how can I get my programs working again?

M = (1+y^2)/((x^2+1)*(1+z^2))

Anyone have any background knowledge on the above 3D polynomial?  Assuming all 4 parameters are real I ploteed some 3D plots & some interesting surfaces are generated.  I imagine this has some physical application.  If anyone has some knowledge on this please respond & include any references you might know of.

Thanks

Hi everybody,

I already discussed my tasks with @Preben Alsholm. Therefore, I decided to share it with you and try to finalize solution.

Actually, I want to calculate heat dynamics transfer between one, two or more rooms. Hence, I used heat balance approach to set the system of differential equations:

In the following code, why is B returned unevaluated?

restart:
A:= a:  B:= 2:
F:= _a-> eval(`if`(A,B,C), a= _a):
F(true);
                               B
eval(B);
                   ...

The "ExcelTools" seems can work based on Excel 2003 format,which can only support 2^16 rows.Excel 2010 format cantains much more rows and columns. So I want to know when maple can support Excel 2010?

Yesterday I’ve updated to the new Version 17.01 and now I’ve the problem that I cannot enter  ‚}‘ and another problem is an exponent e. g. x^2. To enter it I have to write x^22. The first number is not shown in the worksheet.

I hope someone can help me to solve this problem.
