Both:

plots[animate](plot3d, [[r,theta,BesselJ(0,2.40483*r)*sin(2*Pi*t)],
r = 0 .. 1, theta = 0 .. 2*Pi, coords = cylindrical], t = 0 .. 1);

plots[animate](plot3d,[[r*cos(theta), r*sin(theta), BesselJ(0,2.40483*r)*
sin(2*Pi*t)], r=0..1, theta=0..2*Pi], t=0..1);

work fine for me in Maple 12.02.

This page has more examples.

A difference is that it allows a subset of LaTeX code through jsMath.

Maple 14 allows also the syntax:

y:=cos(w*t-arctan(2*s0^3*w, -s0^2*(-s0^2+w^2))):
simplify(y) assuming positive,s0>w;
simplify(y) assuming positive,s0<w;

Maple 14 allows also the syntax:

y:=cos(w*t-arctan(2*s0^3*w, -s0^2*(-s0^2+w^2))):
simplify(y) assuming positive,s0>w;
simplify(y) assuming positive,s0<w;

It works with MultiSeries:-limit:

MultiSeries:-limit(sin(n*Pi),n=infinity) assuming n::integer;
                                  0

Certainly, after ?Re, the argument for both Re and Im should be the same, an expression. And ?whattype includes Matrix as an expression.

In Maple 13 you can use:

m:=Matrix([[1,2],[3,4+4*I]]):
Im~(m);
	[[0,0],[0,4]]

Similarly in LaTeX, there is a command \iota, but I have not seen \jota.

I do not remember reading about "jota" as a greek letter. If this article is correct, it arises in Latin.

In Standard GUI you can use:

`&iota;`, `&omicron;`, `&upsilon;`, `&Iota;`, `&Omicron;`, 
`&Upsilon;`, `&Chi;`;

ι, ο, υ, Ι, Ο, Υ, Χ
