Comment #13 on issue 1319 by asmeu...@gmail.com: constants left out in matching d/dx(g(x)*dy/dx)

I hope you mean tests with the exclude. If you don't add that, the result is not well-defined, and so I don't think we should test it.
By the way, probably the real thing you want to exclude is [f(x), g(x)]. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
