The chain rule of partial derivatives is a technique for calculating the partial derivative of a composite function. It states that if f (x,y) and g (x,y) are both differentiable functions, and y is a function of x (i.e. y = h (x)), then: ∂f/∂x = ∂f/∂y * ∂y/∂x. What is the partial derivative of a function?
