New issue 3628 by smi...@gmail.com: trigsimp introduces extra factor
http://code.google.com/p/sympy/issues/detail?id=3628

In https://github.com/smichr/sympy/pull/25/files I missed two erroneous results that I detail there.

assert trigsimp(coth(2)*cos(3)*exp(2)*tanh(2)) == cos(3)*exp(2)*2

(That factor of 2 should not be there.)
