In mathematics, a critical point or stationary point of a differentiable function of a real or complex variable is any value in its domain where its derivative is 0. Some authors include in the critical points the limit points where the function may be prolongated by continuity and where the derivative is not defined.
As discussed at the end of Lesson 13.1, x = 0 is a critical point of f (x) = x 3 but there is no local extremum there. It was noted that the first derivative (slope of the tangents) is positive on both sides of the critical point, so the sign of the derivative does not change from one side of x = 0 to the other.art III If the first derivative has the same sign on both sides of the critical point, then the function does not have a local maximum or a local minimum at the critical point. Extrema at Endpoints A function's first derivative can only be evaluated on one side of an endpoint of a function's domain.
