It expresses how the rate of change of an outer function with respect to an inner function combines with the rate of change of the inner function with respect to the independent variable. If a function is defined as: <math> y=f(g(x)) </math> then the derivative of '''y''' with respect to '''x''' is: <math> \frac{dy}{dx} = \frac{dy}{dg} \...") Tag: Visual edit
