I don't think sympy can return f for the integral of (df/dx)dx without first differentiating and then integrating. Alan, Yep, that is essentially the sticking point. It relates to the fact that there is no concept of an infinitesimal in the sympy core. I am interested in things like the total differential of f wrt multiple variables. For example: df = (df/dx)dx + (df/dy)dy + …, where these are partial derivatives and implicitly everything but the variable of differentiation is held constant. I use these mostly when doing thermodynamics, but there are other applications. I will see if I can get time to look at what you are doing with galgebra.
