Understanding Stationary Points through Second Derivative

The video tutorial covers the use of the second derivative to analyze the nature of stationary points on a graph. It begins with a recap of the previous lecture, explaining the gradient function and its role in identifying maximum and minimum points. The tutorial then provides examples of finding and sketching gradient functions, and determining the nature of turning points using the second derivative. Key concepts such as stationary points, maximum, minimum, and points of inflection are discussed, with practical examples to illustrate these ideas.
