I use Maple 11 on Windows XP. I try to use it on Windows XP and 2 processors computer, but maple use only one processor for calculation, second processor was not used by mapleserver.exe.

Can I tell Maple force using 2 processors for one calculation task (for example plotting very complicated function)?

I know this is a LaTeX question, rather than a Maple question, but I imagine there's somebody in these here parts who may be able to help...

I'm writing some student notes (using LaTeX) about the use of Maple, and I have several blocks of Maple commands interspersed with their outputs.  I'd like the commands to be typeset verbatim, and the outputs using displayed typeset mathematics.  Also I'd like the whole block to have a gray background.

I want to integrate / differentiate the follow

I am trying to animate multiple plots in Maple.  I know that each of the individual plots work so this cannot be the cause of my error.  Nevertheless, I am getting an error message that I don't understand.

Here is my code: 

We have new problems, running  in maple 12.02, the example of the website
intpak, function
&cmult_opt displays the following message:
"Error, unable to parse."

This problem does not occur if the function is executed in a worksheet with
extension mws.

The other problem is with the function compute_all_zeros_with_plot:

"Error, (in plots:-display) cannot make plot structure from object with name
textplot"

What is the best way to create the equivalent of Matlab stem plots in Maple? (i.e. discrete point plots with a vertical line down to the X-axis - usually used to illustrate a discrete sequence)

Which can be solved simultaneously to give estimates for a and b by Maple

{Psi(1,b)-Psi(1,a+b)} / {Psi(0,b)-Psi(0,a+b)}= s₂/s₁

{Psi(2,b)-Psi(2,a+b)} / {Psi(0,b) - Psi(0,a+b)} = s₃/s₁

I am trying to export a shaded plot with the transparency set to approximately 0.5 so that the gridlines are visible under the shading.  I am exporting it as an EPS for viewing in Ghostscript and/or LaTex.  Here is a simple example.

pf:=plot(x,x=1..5, view=[0..5.5,0..5.5], gridlines=true, tickmarks=[5,5], thickness=2);

pfshading:=plot(x,x=1..5, view=[0..5.5,0..5.5], gridlines=true, tickmarks=[5,5], filled=true, color=COLOR(RGB,.7,.9,.7), transparency=.5);

display(pf,pfshading);

I am very inexperienced with Maple. I have v.12. I was wondering if there was a way to represent diff(int(abs(x), x = cos(t) .. sin(t)), t) in an animation, showing the area under the abs function with the bounds changing in a loop.

Hi,

I am totally new to Maple and need to solve 2 non linear (algebraic) equations with 2 unknowns simultaneously. Can someone please help and tell me how to do this???

Thanks

i have rotated a point on the sphere with rotate command. i found the new points coordinates but I can not use them. How can I use the new coordinates?
thanks..

 

I'm pretty new to Maple. I've been using MATLAB for quite a while but it isn't very convenient for this problem. My first question is if it's possible for Maple to do partial derivatives for a function with two variables. Here's an example of what I am doing.

W = Q*qA - P(qA - (qA-qE)/2) - (1/2)*k1*(qA - (qA-qE)/3)^2 - (1/2)*k2*(qA - 2(qA-qE)/3)^2;

(Maple cleans that up quite nicely)

Now I want to take the partial of W with respect to qA as well as the partial of W with respect to qE. So I should get something like this:

dW = Q*dqA - P(dqA - dqE)/2 - ...

Hay dere. I've come across a nonlinear equation system which i've tried solving in maple through matrices. Maple's own solve function for systems didn't work out (just threw back gibberish at me which i wasn't able to simplify (root of Z etc)) and i really don't know how to approach the problem. Any suggestion on how to solve it would be appreciated.

The problem is as follows:

0 = 22 - 44t + 216t - 66u - 450u + 362u
0 = 150 - 300t + 185t - 450u + 795u - 495u

Hi ,everyone.I have the following eqations I need to solve.However when I tried to run it in Maple it give out the message as shown in title.could any one see this and give some suggestions pls.

eq1 := (q/a)^2+2*q1*f*cosh(-3*p*q2/(2*a))-1-q1^2*f^2 = 0;

eq2 :=  q=a*q1*f*sinh((3/2)*p*q2/a)*q2;

p:=174e6;q:=199e6;f:=0.25;a:=150e6;

solve({eq1, eq2}, {q1,q2});

What is the sum of the central angles of a circle?
