New issue 2748 by [email protected]: your docs, derivative of tan(x) !=
tan^2(x)
http://code.google.com/p/sympy/issues/detail?id=2748
the derivative of tan(x) == sec^2(x)
just thought someone should point that out.
proof: http://www.wolframalpha.com/input/?i=d%2Fdx+tan%28x%29
and http://www.wolframalpha.com/input/?i=tan^2%28x%29+%3D%3D+sec^2%28x%29
its very close but not right.
