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.
I will first explain critical points theoretically. One type of critical point is a local minimum or maximum in the graph. The equation y = x2 has a local minimum at (0, 0). It is a point at which the curve is lower than the surrounding points on either side. In this case, the minimum is also absolute, because it is the lowest part of the whole curve. The second sort of critical point is an inflection point. This is a point in the graph where on one side, the slop is increasing, and on the other side, the slope is decreasing. This can happen whether the curve is increasing or decreasing. Look in the following graph at the first inflection point.
