Chapter 8: Inverse Functions and their Derivatives
We describe the notion of the inverse of a function, and how such a thing can be differentiated, If f acting on argument x has value y, the inverse of f, acting on argument y has the value x. The derivative of the inverse of f at argument x is the reciprocal of the derivative of f at argument f(x).
