Comment #2 on issue 1938 by asmeurer: Recursive trigsimp destroys sums of derivative terms because cse fails on these sums
http://code.google.com/p/sympy/issues/detail?id=1938
It actually probably wouldn't be too difficult to make it just return x0(x, y) for f(x, y).
Another work around would be to just make cse ignore derivatives. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
