Indeed, I agree with you. I created a new issue for it: http://code.google.com/p/sympy/issues/detail?id=1267 I think it is easy to fix, if you'd like to give it a shot, feel free to ask any questions you might have. > > Shouldn't >>>>simplify(sin(x)/cos(x)) > > give tan(x) ? It is maybe related to this isssue: http://code.google.com/p/sympy/issues/detail?id=1036 In general, our trigsimp() function (that handles these kinds of simplifications) should be improved to handle tan(x) well.
