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.
If the derivative changes from positive to negative at the critical point, the critical point is a local maximum Part I If the first derivative is positive to the left of a critical point and negative to the right of the critical point, then f has a local maximum at the critical point.The First Derivative Test to Find a Local Minimum.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.
