1. How do I 
2. Write a maple program to calculate the probability that k cards in 3-dimensonal set game (out of 27 cards) contain a set for k=3…9.

      3  randomly generate 12 cards in 4-dimensonal set game, either find a set or report “no set”.

Can I solve the following two coupled differential equations instead of the previous one in Maple 13?

 with plots

Eq[1]:=3*f(eta)*(diff(f(eta), `$`(eta, 2)))-2*(diff(f(eta), eta))^2+3*g(eta)

Eq[2]:=(diff(g(eta), `$`(eta, 2)))/Pr+f(eta)*(diff(g(eta), eta))

BCs := [f(0), (D(f))(0), g(0)-1, g(25)]

pars := {Pr = 1}

for i to 2 do eq[i] := subs(pars, Eq[i]) end do

eqs := eq[1], eq[2]

vars := f(eta), g(eta)

No that way I could have chosen infinity at 10 or lower values also. f ' will go from 0 to 0 through positive values only. But how can I claim then that my solution is infinity independent. Because if I change the value of infinity whole solution changes.

Moreover at 15.6 the value of f ' is sufficiently close to 0 but value of g (0) is about 0.15 which is far greater than 0. g (0) goes to zero at about eta=25.

So  can I get rid of the problem?  

Is there a way to insert a table of content with the headers of the sections at the beginning of the document? (like in MS Word)

If I click on the link, maple should jump to the section.

It should be updated, if I create a new section or change the header.

My operating system is Mac OS X 10.6.4.   Lately Maple has been EXTREMELY tempermental in letting me "Save As a Worksheet"......I'm NOT talking about the "classic worksheet"

I try to save a file with a different name using "Save As A Worksheet" and Maple goes through the whole "Saving Worksheet" routine BUT NO NEW NAMED file is made!

This is very frustrating.....since it wasn't like this before.

Any ideas?

Hi! I am trying to solve this system:

 but I have a problem.

Hi everybody:

I have the following problem. I obtained an asymptotic solution of a hard problem. The final result is a Maple procedure with five arguments; this function has hundred of term and it works beatifully in Maple. However, we need to convert this solution to C or Fortran code and  I am not able to do it.

After the sentence: Fortan(functionname, optimize, output="filename")

I get the following answer

Error, (in PrintTarget) assigning...

Hi! I have a problem with the total PDE linear system:

F=F(x,y,z,w,h);

X1(F)=F[x]+F[y]+F[z]+F[w]=0;

X2(F)=x*F[x]+y*F[y]+z*F[z]+w*F[w] - h*F[h]=0;

X3(F)=x^2*F[x]+y^2*F[y]+z^2*F[z]+w^2*F[w] - ((z-x)*h+C*(w-y)/(z-x))F[h]=0;  (C=const)

The Poisson brackets are:

[X1,X2]=X1, [X1,X3]=2*X2, [X2,X3]=X3.

I'v tried to solve this system with pdsolve, but F=const is the only Maple's answer. But I am sure that this system has a...

Dear friends,

    The Physics package in Maple is a good tool for quantum physics. However, I came across some problems with the package when I performed a computation. Please see the figure.

The left-hand code (last two lines) shows Amx.Amy.Ket(x,1,1)=”-Ket(x,0,0)”. However, I believe that the answer is wrong; it seems that the negative sign should not be here.

The “am.Ket(B,4)=2ket(B,3)”

I'm going to put this plot into LaTeX, so it'd be nice if the font is similar. Both equations are functions of one variable.

Is there a nice, concise command to do this? Additionally, what's the easiest way to export this graph into a format useable by pdfLaTeX?

Thanks so much!

I'm running Maple 14, if that matters.

the integral
>int(1/x^2-cot(x)/x,x=0..infinity,CauchyPrincipalValue);
with Maple ?
Stars predict it equals Pi/2. Maple 13 easily cracks the integral
>int(tan(x)/x,x=0..infinity,CauchyPrincipalValue)=Pi/2.

Has anyone successfully integrated a 3D plot from Maple (X3D?) into PowerPoint that can be manipulated within a presentation?  I have read an article on Tecplot's (another graphics software package) web site that explains how to export a Tecplot file as an X3D file and then embedding the X3D file into PowerPoint using a X3D plug-in.  See below:

This guy Giorges is using Python and wget inorder to do parrallel downloading
and he is arguing that it is very fast.

http://keramida.wordpress.com/2010/01/19/parallel-downloads-with-python-and-gnu-wget/


Now my questions become

1) Does there exist a simple way that I can use wget without installing it ?
I dont want to bother users of my Maple application with installing a 3:rd party software.
A simple file in a specific location would be ok though

within the attached document, is the idea that I would like to develop with the optimization package.

What's wrong?
I need to minimize (z-Z) ^T.E^-1. (z-Z).
How can you see in the first Call to LSSolve worked. By introducing objectivejacobian I have problems
