WebThe definition of a critical point is one where the derivative is either 0 or undefined. A stationary point is where the derivative is 0 and only zero. Therefore, all stationary points are critical points (because they have a derivative of 0), but not all critical points are stationary points (as they could have an undefined derivative). ( 3 votes)
