hi, i have a function in seri's with one unknown parameter and i want to solve it for this boundary condition : f(infinity)=1

I use pade approximation but in my case it doesnt work. i want to know is there exist other  method in maple for this problem. for example other rational function.

thx

for simple case 2*2,  A = matrix([[0,-1],[1,0]]);

using A, i understand f(x,y) = f(-y,x)

where do other case f(-x,-y) and f(y,-x) come from?

any command to list all cases with input a matrix A?

if A has more dimensions, what will the cases be ?

Hi , how do I get the binomial expansion of  1/sqrt(9+4*x^2) .  I am using expand(expression,binomial) . But Maple just

returns the expression.  Thanks .

how to x1, x2 ... with xi in procedure?

b := 1;

for i = 1 to 3 do

     b := b*1/(1-xi);

od;

but xi can not represent x1, x2, x3, which commands can present x1 x2 x3 ?

which package containing command to find prime ideal and quotient of ideal?

How to assign value to matrix in procedure?

with(ArrayTools):
kontraHom := proc(M, s)
dim := Size(M);
n := dim[1];
m := dim[2];
R := [][];
for i from 1 to m do
    for j from 1 to s do
        for k from 1 to n do
            R[(j-1)*n+k,(j-1)*m+i] = M[i,k];
        od;
    od;    
od;

I'm running simulations in which I produce many plots at once, the purpose being to compare differences as parameters are changed. I'd also like to use some of these plots for publication. I've had problems getting good-looking 3d plots. Here's a strange thing I noticed.

Export the graph by mouse-clicking, export to bitmap:

EDIT : IMAGE POSTED IN MY COMMENT BELOW

Export the garph by executing a plotsetup('bmp') command.

1. How many and which file format can be used to save a list of formulas?

2. how to append to above file?

i would like to let c# program to read the formula in the saved file

Hello,

I am going to solve 2D Laplace equation for function Φ(x,y) in a rectangule which has a*b dimension, yet its boundary condition, at least for me, is rather complex. Here it is:

d/dx(Φ)=0  at  x=0 , x=a

Φ=1  at  0<x<a/2 , y=0   

d/dy(Φ)=0  at a/2<x<a , y=0

what is the command to computing syzygy ideal in maple?

Hey,

I have a set of Matrices of the form [a,b,c,d], now I since the standard = doesnt work with matrices, but I have to instead use verify I wanted to ask how I write a function that returns true or false depending on whether a new matrix is already contained in the set. Or otherwise I want to filter the set so that I only have each matrix once.

Thanks!

Hello all,

I ran this code a few weeks ago and it worked perfectly.. but now that I try it.. it says 'too many levels of recursion' on maple 14 and 'lost connection to kernel' on maple 15. Can someone give me a hint as to what is going on?

I have also attached the file :  allslopes2.mw

Any help is really appreciated

Dear Sir,

I attached an example file to this email via speedyshare, please check it out, also please see the following pasted warning message from that file.

http://www.speedyshare.com/files/29834055/DSsolve_range_example.mw

My analysis gives a warning. Though I have results that look reliable, it is nasty to receive this kind of warning...

Actually what this warning means?
Does it affect the results badly?
How about reliability...

I need to cut a circle into equal pieces like a pizza, but how do I do this through code?

Also, I need to be able to find the area, angle, and arc length. Is this possible through code?

Thanks!

I need to create an ellipse and an ellipsoid (ellipse in 3D) through code. How would I be able to do this? Can someone please give me an example for each?

Also, I will need to create a line for an ellipse and a plane for an ellipsoid that intersect. Would I be able to find the intersecting points? Would I be able to find the function for the curve line that is created when a plane intersects an ellipsoid? Also, how would I find the surface area and volume...
