Comment #4 on issue 1562 by mattpap: Have trigsimp apply factor and Poly.cancel() to sin's and cos's http://code.google.com/p/sympy/issues/detail?id=1562
> code that runs has() on the solution and Poly().has() fails. One technical thing. Don't confuse polynomial (Poly, an algebraic entity, no matter if this means really something in current implementation) with an expression. If you have complicated symbolic manipulation to do, do it on core level, because this is why we have sympy.core. However, if you have efficiency demanding algorithms which can take real advantage of polynomial functions then go to sympy.polys. In fact I didn't plan to continue support for Poly.has in new implementation (there will be, however, functions for evaluation and composition). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
