Comment #3 on issue 3819 by [email protected]: trigsimp gives bad results
for non-commutative symbols
http://code.google.com/p/sympy/issues/detail?id=3819
I put a debug statement in strategies debug function and nothing in the
trigsimp sequence generates an error -- all the Trues are testing whether
input equals output.
