When I type a statement like a := vector([cos(arctan(x))]);
Maple outputs it in the form a := 1 / sqrt(1 + x^2)
I know they are equivalent, but is there a way to force the output to
look like cos(arctan(x))?

Regarding command line string assignments, eg;
maple -c "str:='/examples/ab1'".
Maple complains about this syntax.  I'm unclear
about escaping the "/" and whether it needs end

I Sqrt[3]])] + Log[(2 + Sqrt[3])^(15 I)] + Sqrt[3] Log[

Is there a way to derive range interval for a complicated expression
based on the bounds of parameters?
Let's say I have a function f(a, b, c, d, e, f, g, h, i, j, k) where a
is the variable and b, c, d, e, f, g, h, i, j, k are parameters.

I'm using Maple 10 and I would like to know an up-to-date procedure to
export the final elements
of my current Maple Calculation Sheet to Matlab. Quickly, running the
Maple code leads to

I have difficulty in taking fourier transform of a function f(t).
The function f(t) is not integrable. Through analytical analysis, f(t)
behaves asymptotically the same as a*log(t)/t
for t-> +infinity; and f(t) behaves asymptotically the same as b*log(-

Let f : R^2 ---> R,  (x,y) |---> f(x,y), a map of two variables.
Is it possible to calculate, with Maple, the limit of f at a point (a,b) \in
R^2 ?
For instance : f(x,y) = x^3y / (x^4 + y^2). I calculated (on paper) that

is there a more readable alternative for assigning a vector to the j-th column
of a Matrix?
Given:

Rectntly, i wrote a program using matlab. in the code written by me, i
use a function erf(x), while the x used by me is complex arguments, so
the matlab cannot give the results. i realized that the maple can
realize this. so i use the maple function in matlab, but there is some

I'm trying to make a 3D plot of a surface, and the surface has several
poles.  As a result, the z-axis goes way past what I want to plot, and
I don't get the resolution I would like.  Is there a way to define the
range of the z-axis, just as there is a way to define the range of the

I have a complicated expression in Maple. I would like to export this
expression in to Java code.
In order to do this I use the codegeneration package.
I.e. :
