removing hacks is always good news, but I do not agree that
sin(x)**2/cos(x)**2 is a valid answer.
By definition, trigsimp will try to return the simplest possible
expression, and although 'the simplest p

Previously trigsimp() failed to simplify sin(x)/cos(x) to tan(x) and similar
things and
nice patch. +1
