Maple does not simplify the expression -2*Pi*sin(Pi*a)/(-1+cos(2*Pi*a)). How can I make it do so? 

Thanks,

Maple 15 64-bit on Windows 7

Hi! I'm running Maple 15.01 64Bit on my Xubuntu 12.04.

I also got Maple 15 installed on my Windows7 64Bit computer to verify the results.

So let's see what is going wrong:

What does work?

int(x^n, x);

Gives me on both machines the correct result:

Hi,

Question 1:
In matlab, i write "Ck=zeros(18,18,6)" which will give me the answer Ck(:,:,1), Ck(:,:,2), Ck(:,:,3)... Ck(:,:,6).
I tried writing Ck:=ZeroMatrix(18,18,6) but it doesn't work. May I know what is the right way to write it please?

Question 2:
Relating to the above question, I now have several Ck matrix, Ck1, Ck2, Ck3... Ck6. and also several P matrix, P1,P2,P3...P6. Each Ck and P matrix are 9x9matrices. How can I write A:=Ck*P to give...

The input signal is given above. I don't kown how to get ti in MapleSim whether use custom component or not. Is there anybody can do me a favor. Thank you very much.

Hi, I have a list of 15 numbers. I am trying to fit it into a triangular matrix. It will be a 6x6 matrix with zeros in the diagonal lines.

The first number will go into the M₁₂, second number will go into M₁₃, followed by M₁₄... then, the six number will go into M₂₃, seventh number into M₂₄ and so on.

Here is what I got so far:

Z is a diagonal 6x6 matrix

node:=3
for i from 1 to (node*2-1) do

Hello. I wanted to solve a parametric 16*16 determinant. My first question is, whether or not it can be solved?! after that when I tried to open my work in progress I got the following message: "
There were problems during the loading process. Your worksheet may be incomplete". Could someone help me recorver my work? Thanks in advance.

Hello,

we have to create program which shows chemical concentration changes, but this concentration depends on time and distance along the longitudinal axis. So we have to put numbers into the left side 41x41 matrix from 3 equations:

A:=1, B:=1,E:=0.2, Δx:=0.25,Δt:=0.025.


first when i=0;

Hi, I have a 18x18 matrix called Lambda.

I'm trying to get NewLambda which consist of "(Lambda(1,1)-Lambda(2,2))/2", "(Lambda(2,2)-Lambda(3,3))/2", ....,"(Lambda(17,17)-Lambda(18,18))/2".

Here is what I wrote :

for i from 1 to 17 do
for j from 2 to 18 do
NewLambda:=((Lambda(i,i)-Lambda(j,j))/2;
end do
end do

But it doesn't show me the NewLambda. Please help. Thanks

I want to omit the independent variable

for example:

> alias(f = f(x+y, z+y));
print(`output redirected...`); # input placeholder
                               f
> f1 := z = f(x+y, z+y);
print(`output redirected...`); # input placeholder
       ...

How to edit the tex generated by the maple:Put the one equation into several rows

For example

This code p57.txt  can get the below picture

But what I want is

Hello everyone.

an equation or a table can have a label and can be later referred to by using insert->label. Can we do the same for inserted images? Like Figure 1, etc.... A workaround is to insert the image in a 1x1 table and reformat the caption. But I am not sure that's the ultimate solution.

Another related question: can an equation that is just in the 2D math mode that is not meant for execution get a dummy label like (*) or (**) or something like that?

Based on the title, once again I'll mention that the programm that I have been made by using

Maple14 could not run faster.

The function of Maple should be running effectively compared to others.

Hereby, I'll attach the programm for your further action.

That's all, thank you.

Does anyone know how to switch a joint between having a prescribed motion driver and acting as a passive joint? More specifically, I am building a bed of spring to serve as a model for haptic feedback on a Phantom Omni device. Therefore, I need to read the position of the device (which is not a problem) and then based on the position of the device calculate a force to feed back to the device.

Consider the simplified example below. In one situation I may need to give...

The fourier transform of a signal results in an answer with Real and Imaginary parts.

When I want to plot those results, is it correct that I need to take sqrt(Re^2 + Im^2)  ? 

However, if I just plot the Real parts of the answer why is that not correct?  Of course half the answer is missing, the imaginary part? but since it's imaginary it's not really that real and so why should it be included? 

Can someone shed some quick light on that subject for me?
