Ok hello everyone and thank you in advance.
I have 2-3 difficulties in a maple plotting.
I'm trying to plot two fairly easy surfaces in maple 3d. 
What I want is:
3 standard axis, x,y,z with y vertical and z coming out of the screen(obviously you can turn it and stuff.)

Two surfaces:
On with y = (1/x), z=free;
The second with y= 2*x(1/z);

Hi all,

I'm editing a scientific document in Maple document mode. I'd like to assign a mathematical result to a variable, which is a 2D-math expression.

An example:

I'd like to assign the result of

to the expression

ans:=CompleteSquare(x^2+2*x)

                                             ans := (x+1)^2-1

ans1:=CompleteSquare(x^4+2*x^2, x^2)

Error, (in Student:-Precalculus:-CompleteSquare) arguments after the 1st should be a name, function, or a list or set of names or functions...

Hi,   I want to plot a vecotr 100x1   with neumerical data. Could anyone help me.

> f (x) =  x^3+2*x+1
                 
> NewtonsMethod(f(x), x = -.5, output = sequence);

              -0.5, -0.4545454546, -0.4533983368, ...

I was successful @ splitting the coupled eq into the 3 constituent PDE's but have been unsuccessful to get MAPLE to generate the characteristic solutions except for the 1st one for X which is the basic solution to the Helmholtz eq.

Can someone with more savy with MAPLE verify whar I have so far & advise me how to proceed to solve for Y & Z?  I have uploaded my file.  My expereince with MAPLE vector calc package is limited.

appreciate the assistance

Hi, every body,

When I use the two orders stackmatrix and augment. It is ok. But, when I try to use the reslut matrix in any place no matrix appears.

Could any one help me.

Hi everybody:

I am running an application which involves solving symbolically an ODE over a three segment domain and then adjusting the constants of integration to satisfy boundary/continuity conditions. I wrote the code in document mode and noticed that it takes very long to execute. I resurrected the old worksheet-based code which does basically the same thing and it runs much faster. Of course the code in both cases (due to evolution of both software and user) is not exactly the same.

how woulud i plot this for maple 11

2(x^2+y^2)^2=25(x^2-Y^2)

I tried to solve a PDE-BVP :

D[epsilon]*diff(C[a](z,t),z,z$2)-(lambda)*R*K-S=0;

BC C[a](0,t)=C, (d(C[a])/dz)(z=-z0)=0;

Request to guide me how to write maple code for Boundary conditions.

I was about to post this as a "How-do-I" question, but while composing my question, I stumbled upon the solution.  In case this "discovery" would be useful, I'm posting it here.

For some coursework, I'm developing fitting sinusoids to experimental data (poor-man's Fourier Analysis).  At one point, I do a "brute-force-least-squares" computation, one step of which involves computing the sum of a sine over N equally-spaced intervals around the circle.  This...

Maple does not find the product
