Hi everyone.

I have a very particular situation here: I'm running a series of programs that grab string output from command line Maple as plaintext. For this reason, I don't have the normal Numerical Format dropdowns, etc., available to me for this issue.

Hi folks,

I'm trying to get the fundamental solution of

-diff(A,t)+a(x,t)*laplacian(A,[x,y,z])=0;

I had some troubles entering the code here, so I uploaded the maple commands here: http://pastebin.com/m2765fda0

when I call eval(phi(x,t,xi,tau));  to calculate the fundamental solution, I always get the error 'Error, (in w) numerical exception: division by 0'.

Shouldn't my assumptions avoid this error?

Thanks for your hints!

Dear all,

     How can I fix the ratio of height to width as 0.618 when plotting figures ? The command scale=constrained seems not appropriate   If  someone  knows how to realize it , please tell me ASAP. Thank you very much ! 

Kindly regards,

Yours

f := sec(x)^2;
Int(f, x = 0 .. 5*Pi*(1/4)) = int(f, x = 0 .. 5*Pi*(1/4))

I enter the above in Mape 12 Student Edition, and the answer is infinity, but it's obviously 1.

How can I get Maple to display the obvious ?

I am using Maple 10 and i want to export as "jpg" files multiple columngraphs. These columngraphs are generated from:

>for k  from 1 to 100 by  5 do

ColumnGraph(points[k],color=blue,axes=BOXED,thickness=2,print(t=k),view=[0..26,0..0.1]);

od:

Then i use the command :

>for k  from 1 to 100 by  5 do

plotsetup(jpeg,plotoutput=`k.jpg`);

od;

but exports only one file called "k.jpg" .

Hello clever people,

Here's an easy question for you all I'm sure (though as a novice I've been stuck on this for hours).

Why is it that when I'm using Maple 12 some of my assignments don't seem to work while others do? Most of the time I don't have a problem assigning matricies and vectors but quite often Maple doesn't seem to want to recall the contents of a variable when performing operations.

Dear all,

     How can I insert mathematical notaions in Labels when plotting figures ?  I never encounter this problem, but now it is urgent for me to resolve it.  In labels, I depict the meaning of axes and need to use some mathematical notatioons.   If  someone  knows how to realize it , please inform me ASAP. Thank you very much ! 

Kindly regards,

Yours

Hello everybody, I come form Denmark where i recently began at the local gymnasium(school).

Here i have math at the highest level possible and I have been told to buy a TI-89 titanium, but i would much rather like to use maple because it only costs half of what the TI-89 costs, and i already have a MacBook.

But the question is do any of you know any good books about the use of maple. Are there any down sides about using maple in comparison to using a TI-89.

Thanks in advance, Daniel Kristensen.

Hi,

this problem has been bugging me for quite some time now, and I have seen other people struggling with it as well.

When I work in Maple 11 and I want to insert a new section, he jumps all the way to the bottom and puts the new empty section there, where I don't want it to be.

I've also had similar things when I press the "T" to insert Text.

How can I solve this? Many thanks!
