Yes, I think most of the logic should be in sympy proper. I think it could be turned on with something like The only thing that I am not sure is if it should go into sympify or some other function, because it can be ambiguous, e.g. xy vs. xy (x*y vs. xy) But in any case, I want it to be able to handle most of the syntax that people use out there (including the latex one). > > As for showing steps for integration and so on, does anyone know if > there are any general purpose algorithms for this?
