Comment #7 on issue 2247 by [email protected]: Problem with coth http://code.google.com/p/sympy/issues/detail?id=2247
Sorry but this computations are absolutely accurate. And they were in the module long ago, I just add the part which was missed.
Oh, dear I can recommend you some good books about trigonometric and hyperbolic functions and about Rieman's surfaces too, so feel free to contact me.
The prove is even more simpler: acoth(x) = t => coth(t) = x tanh(t) = sinh(t)/cosh(t) = 1/coth(t) = 1/x -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
