New issue 3204 by [email protected]: Simplifying of the sum of tan(x) and cot(x)**-1.
http://code.google.com/p/sympy/issues/detail?id=3204 Simplifying the sum of tan(x) and cot(x)**-1. trigsimp must handle the linear combination of tan(x) and 1/cot(x). The same and for the hyperblic tanh and coth. Desired:
trigsimp(tan(x) - 1/cot(x))
0
trigsimp(3*tanh(x)**7 - 2/coth(x)**7)
tanh(x)**7 -- You received this message because you are subscribed to the Google Groups "sympy-issues" group. To post to this group, send email to [email protected].
