Comment #10 on issue 588 by smi...@gmail.com: simplify should be better at
detecting repeated factors
http://code.google.com/p/sympy/issues/detail?id=588
This now gives
h[3] >>> integrate(x**2 * exp(x) * cos(x), x)
exp(x)*sin(x)/2 + x**2*exp(x)*sin(x)/2 - x*exp(x)*sin(x) -
cos(x)*exp(x)/2 + x**
2*cos(x)*exp(x)/2
h[4] >>> simplify(_)
(-cos(x) + x**2*cos(x) + x**2*sin(x) - 2*x*sin(x) + sin(x))*exp(x)/2
h[5] >>> factor(_)
-(1 - x)*(-sin(x) + x*cos(x) + x*sin(x) + cos(x))*exp(x)/2
Can this be closed? There is no trim, btw.
