Hi, I am new to sympy. I try to derive an equation of that form: T = k * x' x if a function of time ; x = f(t) x' is diff(x, t)
I would like to get T2 = diff(T, x') T3 = diff(T2, t) Is it possible ? I checked the documentation, but couldn't find a way to do that. Thanks for helping ! Philippe PS: I try to get it with T = m * f(t) print diff(T, f(t)) does not work :/ ValueError: Invalid literal: f(t) is not a valid variable -- You received this message because you are subscribed to the Google Groups "sympy" group.
