Derivatives of inverse functions

In calculus, if y = f(x) then it's derivative y'=f'(x)=dx/dy. To find the inverse function of y = f(x), it is simply x = f −1(y), and the derivative of this inverse function is going to be dy/dx. So the these two derivatives are reciprocal, in other words dx/dy * dy/dx =1.
