Hi

I have created a figure in Maple 15 using Plots:-display() command.  I want to save the combined figure (given by display) as a .eps format. I can do this by right-click on the image>export>Encapsulated Postcript. I need to run the code several times so that it produces a different image each time(by changing variables). I have to then click on the image and drag it so that it becomes the appropriate size I wanned.

My problem is that it is difficult...

Mrs Bopha, used phone that had 7 numbers. Som didn't clear her phone number.Som remember 4 numbers in the first that had 9 ,8 , 7 and 7 Som didn't clear serial number 5 about 1 or 2.For serial number 6 didn't remember. But Som remember that serial number7 equal 5 minus serial number 6.How many time that Som  should be chose right phone 's number to Mrs Bopha?

I intend to calculate the eigenvalues and eigenvectors, but for the same matrix when i executed the Eigenvectors command in mapple twice the eigenvalues generated are same both the times but the values of eigenvector are infinite at one instance whereas they are in numeric domain in the second instance.

Can anyone please tell me why this is occuring?

Hi.

I want to solve two varibles from a vector crossproduct equation, but receives a failure massage no matter what i do.
The equation is the one below and i want to solve for Gx and Gy.

Really hope you can help.. THANKS!

The sine wave in Maple 16 is shown as following

It's obvious that the second one is smoother than the first one,I want to know how to make curves smoother in Maple 16.

Hi,

  I have a .txt file created from maple. I want to read some data using maple. The content of that .txt file is

....

some word,                     -7
                    -0.25333 10

...

some word,

The second graph is incorrect. The reason?

plots[polarplot]([3+cos(4*t), 2-cos(4*t)], t = 0 .. 2*Pi)

Hi,

I would like to know if it is possible to make Maple do the following:

Suppose you have a function dx:=1/((x1-x3)^2+(x2-x4)^2) and we want  diff(dx,x1), is there a way to obtain: *-(2*x1-2*x3)/((x1-x3)^2+(x2-x4)^2)^2 instead of -1/(x1^2-2*x1*x3+x3^2+x2^2-2*x2*x4+x4^2)^2*(2*x1-2*x3)?

Basically how to keep the denominator in a fatorized form and not expanded?

Thanks.

Dear Sir,  I want to know why the procedure  appear the error : (in U1) unable to execute add.

My procedure:

Can anyone tell me how i can compute the correct partial derivatis of this function? I need to compute the partial derivative with respect to P_j,k but since I am summing over 'j', it does not compute the chain rule properly. 

Hello,

After we solved two equations we want to plot them with two sliders. I am trying to have two sliders for k and mu. I followed what this link suggested:

http://www.mapleprimes.com/questions/119732-How-To-Code-Sliders-To-Make-It-Easy

But I get this warning:

Warning, `p1` is implicitly declared local to procedure `myplot`

In the following script, I am trying to understand why evala returns an error. It returns

                Error, (in evala/Reduce/nf/indep) invalid arguments to coeffs

in a couple of places. I tried, and I can get around the errors by doing it a complex way, but it seems like I'm just not using evala correctly. Perhaps someone can comment? I'd very much appreciate it.

Hello,

tryning to put some text on plots,

and wonder how can I separate text decoration of variables.

For example a circule with radius

and center in

    Why the zeta1 does not plug in numerical calculation.

hello, everyone,
the attached pdf file contain four models, I can't get the solutions of last three models.
help, thank you in advance.
