New issue 3799 by asmeu...@gmail.com: trigsimp goes too far?
http://code.google.com/p/sympy/issues/detail?id=3799
In [3]: simplify(exp(x)*sin(x)/2 + exp(x)*cos(x)/2)
Out[3]:
___ x ⎛ π⎞
╲╱ 2 ⋅ℯ ⋅sin⎜x + ─⎟
⎝ 4⎠
───────────────────

I wonder if trigsimp is being a little too smart for its own good here. I
would have expected just exp(x)/2*(sin(x) + cos(x)).
