Comment (by cremona):
To me it looks as if most of the extra time is in the symbolic gcd calls.
But seriously, why on earth does potting a simple trig function involve
anything as sophisticated as creating homsets? And why also are any gcds
being computed? Is it that for each of the values t which are being
iterated over, which are rational multiples of pi, the evaluation of
sin(7*t) and cos (30*t) is being much too clever when all that is needed
is a low-precision numerical value?
