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...

I am tring to solve a PDE system with four equations that its unknowns have three independent variable.

Is it possible to solve this system numerically?

I currently need to cut a sphere into equal parts becuase I am carrying out an investigation for a school assignment. However, I do not know how I can cut the sphere into pieces in Maple, which I have been told it needs to be done through code. I will need to know how I can cut it so I can carry out my investigation by cutting it into different number of pieces. For example, cutting a sphere into half, so one piece would be a hemisphere.

Also, I will...

Can you please help me:

1 - What "0.0000591392596494206" stands for?

2 - What "the matrix 4 rows by 1 column" stands for?

and

3 - What "460" stands for?

I'm looking for information on the x3d format, with a view to converting x3d to 3d-pdf.

1. x3d formats are available from standard gui by right-clicking to "export".  How can you use plotsetup to access the "Extensible 3D" format with a line of code?
2. what x3d viewer do you recommend?
3. do you have any tips on converting x3d to pdf?

Let me elaborate to provide context to my questions. In a previous post (

HI,

I am trying to solve for fourier coefficients but can't figure out the error in the code. Need help to debug the code.

Also if possible how to find the harmonics in the curve defined in the code.

following is the website from where i got this code

fouriercoefficient_h.mw

Here is a simple version of the code:

restart;
plots[textplot]([4,2,q[n]]);
plotsetup(gif,plotoutput=`p.gif`);
plots[textplot]([4,2,q[n]]);
plotsetup(default);

I am trying to write a quaternion package, I also want it to be able to multiply quaternion polynomials where the unknown "x" remains on the right of the coefficient. the I,J,K rules are standard quaternion rules.

define(M, 'flat', 'multilinear', 'identity' = 1,
M(I,I)=-1, M(J,J)=-1, M(K,K)=-1, M(I,J)=K, M(J,I)=-K, M(J,K)=I, M(K,J)=-I, M(I,K)=-J, M(K,I)=J,
M(a::anything,b::anything*x)=M(a,b)*x,
M(a::anything*x,b::anything)=M(a,b)*x,...
