Comment #1 on issue 2662 by asmeurer: conjugate(x).diff(x) is wrong http://code.google.com/p/sympy/issues/detail?id=2662 Changing this does indeed prevent some integrals from working, like integrate(conjugate(x), x). We really need to separate the derivative used by the heuristic Risch algo

Comment on Motivation in sympy

Comment by brett_...@optusnet.com.au: I have just started using sympy. I've been using it to equations of motion using the Langrangian formulation, so I just need to state the KE and PE formula and let sympy do the tedious and quite error-prone (when done by hand) differentiation. It's bri

Re: Comment on Motivation in sympy
