Hello, I am trying to take the derivative (d/dx) of a very messy equation that is more easily expressed initially as a function of y, then y and a function of x. Rather than have to substitute and expand, can a set of equations be input and instructed to find a derivative wrt x? (A little bit new to Mathematica) Thanks. Will
