I find that Maple leaves things like sin^2(x) + cos^2(x) as they are, which is giving me some very long and complicated looking expressions that are often just simple things.
I'm sure there must be a way of sorting this out but I can't find anything.
Also, on a more theorectical note, does anyone know why Maple doesn't do this automatically, or at least have a pre-programmed command to simplify such things?
