I have a question regarding polygons.
There is an example in the documentation (I omitted color):
with(plottools):
l := polygon([[0,0], [3,4], [3,1]], linestyle=3, thickness=2);

Does anyone know of a Maple program for calculating the conductor of an
ellptic curve? Ideally it would be as little like Apecs as possible,
consisting of a function which inputs a curve in standard 5-element
list form and outputs a number.

I have two equations: p=x*y*z and x+y+z=100. How can I plot the surface
defined by points x, y and z that satisfy these equations?

I'm very confused by the answer of Maple 9 and 10 to the following
piece of code (either it is a bad bug, or it is a very confusing
behaviour). Try:
A:= Matrix(<<-2, 1>|<1,-2>>, storage=sparse);

I want to solve a system with 2 maximizations and some constraints
is it possible with Maple V9.5, with the package optimization and the
function maximize ?
Max f1(x,y)

Why is 1^infinity equal to 1? shouldn't be undefined?

Is there a short way to assign a value to a sequence of variables?
Apparently something like
x1, x2, x3 := 0; is not working and I have to re-type all the three
zeros as x1, x2, x3 := 0,0,0;

Is there a way to list all the active variables?
That way if I have mis-typed one, it shows up easily (two variables
with similar names separated by one letter or underscore).
It seems like a useful troubleshooting tool. Matlab has it with their

I have for example:
N := 4;
q := 2;
Then i do:

How to find the singular part of (1-z*t)^(-a) in t=1/z where a is complex?

using Maple 10.04:
 Sum(pochhammer(a,n)/n!,n = 0 .. infinity): value(%);
                                 0
 sum(pochhammer(a,n)/n!,n = 0 .. infinity);

Tested in 10.03

Dear group,
I am using Maple 7 to solve a quadratic eigenvalue problem of the type:
A*lambda^2+B*lambda+C=0
A and C are symmetric matrices; B is a skew symmetric matrix.

Running Maple 10.03 on a Mac:
restart;
f:=p*x^(p+2)-(x+1)^2/3-7*x^(p+2);
                  (p + 2)   1        2      (p + 2)
