Comment #25 on issue 1038 by hacm...@gmail.com: (sin(x)*cos(x)).series(x, 0, 1000) takes forever
http://code.google.com/p/sympy/issues/detail?id=1038

If I were to derive this particular series by hand, I would convert it to sin(2*x)/2 and then then nth coefficient would be trivial to find. More generally, if I were to compute a,Taylor series, I would try to get the function into a sum of things that were easy to compute series coefficients for, then add the coefficients of the individual series. Is there some way to apply this approach in SymPy?
