Trying to use Maple to perform some trigonometric transformations, I found a good introduction to Maple: MCS 320: Introduction to Symbolic Computation of the Department of Mathematics, Statistics, and Computer Science @ the University of Illinois at Chicago. It have some lines about the Maple function, which give that kind of informations: 
>> trigsub(cos(2*x));
[cos(2*x), cos(-2*x), 2*cos(x)^2-1, 1-2*sin(x)^2, cos(x)^2-sin(x)^2, 1/sec(2*x), 1/sec(-2*x), 
(1-tan(x)^2)/(1+tan(x)^2), 1/2*exp(2*i*x)+1/2*exp(-2*i*x)]
format
