RE: Weird answer for d(sin(sin(x)))/dx
Ah yes. It seems cos(x)*cos(sin(x)) is one of those cases where simplify() makes things more complicated.

Going the other way, the HP 50g's SIMPLIFY does get from the long form back to cos(x)*sin(cos(x)), so there's a sort-of "regression" here. (Well, assuming the Prime represents a functional continuation... which probably isn't entirely fair!)
