This has been discussed before. We want both the behaviors of solve and dsolve. i.e., we want both
>>> solve(f(x).diff(x) - f(x), f(x)) [Derivative(f(x), x)] and >>> dsolve(f(x).diff(x) - f(x), f(x)) f(x) == C1*exp(x) I don't like the idea of using f instead of f(x) as a flag. What happens if there is also f(y) (and even f(y).diff(y)) in the equation? Besides, this goes against what we are trying to do with https://code.google.com/p/sympy/issues/detail?id=3560, which is to simplify solve(). Merging dsolve() and solve() would also require merging all their options, and making sure that they are consistent and don't conflict. Keeping the different types of solvers separate is a good thing, in my opinion. Aaron Meurer On Mon, May 27, 2013 at 12:22 PM, F.
