Maple's plotting capability is just not for heavy duties. It easily
crashes.
Anyone knows a good strategy for piping out data (or just writing out
data),

Given the series transformation:
b_n  =  Sum[ (a_m)^n , m=0..infinity]
so for example it transforms a_n=n into b_n=zeta(n) and a_n=n^2+3 into
some other series.

In Matlab, numerical overflow is handled using
Inf. For example, sinh(800.0) = Inf in Matlab. The
same expression in Maple is handled differently,
namely  sinh(800.0) = 1.363187286*10^347 in Maple.

What is the solution of this system :
{4*x1^2+x2^2=u^2, 4*r^2-x1^2=v^2};

how to get a probability of an element form a list of observation?
data:=[3,3,4,5,5,5]; u_:=describe[mean](data);
s:=describe[standarddeviation](data);
prob(3,data) should give 2/6

Help please!!!
I have generated the following:-
A[1..2,1..2]:=<<1,2>|<5,6>>;
What is the script to extract the entry say in A[1,2]  (i.e. 5 in this

I am new to Maple - can someone out there please help.
I can generate an alpha numeric array  e.g. A:=Array(1..4,1..3);   but
at present I have to enter data  1 location at a time.  Is the script
that would allow me to enter data into the 3 columns first row in a

I have a Matrix (from LinearAlgebra), where the coeffs depend on a parameter, say p.
How can I get the Matrix, which contains the differentiated (w.r.t p) elements.
I need something similar to Map2 ?
Many thanks for a hint,

First of all, I am working on an American Mathematical Monthly problem,
so I won't be able to post all of my actual code. Second of all, I did
some searching of the archives and found the thread "How to substitute
matrix entries?", which helps a little but not entirely.

Hello, I am trying to compute symbolicliy a determinant of a matrix
16x16 of the following form:
Q:=matrix([[mu1, mu2, 0, mu3, -theta1, theta2, 0, 0, -theta1, 0, 0,
theta2, 0, 0, 0, 0], [mu2, mu1, mu3, 0, -theta2, theta1, 0, 0, 0,

Is there any way in Maple to do the following:
Give some value range to symbolic terms in a function and then get a
simple approximation of that function having some of its insignificant
terms neglected?

I have six rational functions f1,...,f6 in 4 coordinates:
f_i \in Q(x,y,z,w) for i=1..6.
I want to know if one of them, say f1 as an example, belongs to the
field Q(f2,...,f6) generated by the other 5 functions.

I met with numerical difficulty in computing the moments of the Weibull
probability distribution function,
In Matlab, "wblpdf(x, a, b)" denotes the probability density function(the
derivative of the cumulative distribution function), and "wblcdf(x, a, b)"

restart;
 f := x -> 1/2*(1+x*(Psi(-1/2*x+1/2)-Psi(-1/2*x)))*sin(Pi*x)
           *(1-x*(Psi(1/2*x+1/2)-Psi(1/2*x)))/(Pi*x);
 limit(f(x),x=infinity);  # Maple V R5 responds: 'undefined'.

I was just wondering whether anyone knows if updating from Maple 10.04
to Maple 10.06 (on a PPC Mac) is a good idea.  There's one unfavorable
report on VersionTracker, saying that the update trashed Maple - any
experience here to report?
