Comment #2 on issue 1617 by tan2tan2: tan(x)*cos(x) and cot(x)*sin(x) are
not simplified
http://code.google.com/p/sympy/issues/detail?id=1617
Great, it's really helpful. The attached patch simplifies the following
formula:
a * tan(b)**c * cos(b)**c --> a * sin(b)**c
a * cot(b)**c * sin(b)**c --> a * cos(b)**c
a * tan(b)**c / sin(b)**c --> a / cos(b)**c
a * cot(b)**c / cos(b)**c --> a / sin(b)**c
