Comment #1 on issue 3237 by ness...@gmail.com: cancel() should use ratsimpmodprime when necessary http://code.google.com/p/sympy/issues/detail?id=3237 This works, but it is going to be just as slow as trigsimp_groebner. The cancellation algorithms should be able to work in QQ(i), or

I implemented a new option polynomial=True. As explained in the docstring, this essentially just applies reduced(). If given a polynomial, and using a graded order (as by default), this is guaranteed to return a *polynomial* equivalent to what we started with, of minimal degree, but no other
