Stationary point

This lesson is intended to help the 'A,' level students to master the topic of STATIONARY Points which states in calculus, 'a stationary point or critical point of a differentiable function of one variable is a point of the domain of the function where the derivative is zero. The slope of the graph at that point is zero. Informally, it is a point where the function "stops" increasing or decreasing. There are plenty of clear diagrams in this lesson to demonstrate the exact concept of this important and interesting topic.
