Differential Calculus is all about derivatives of functions. This class helps you understand what is meant by the derivative of a function before you learn how to find derivatives using various techniques presented in this section.

Differentiation can be used to solve a wide variety of types of question. In this class we look at one of the most common applications of differentiation which is to find the equation of a tangent to a curve at a given point. 

One of the most important points of any function is where it changes direction. Such points (maximums, minimums and points of inflection) are called stationary points. In this class learn how to use the derivative of a function to find the stationary points. 

As well as finding stationary points we also want to know what type they are (maximum, minimum or point of inflection). This is called finding the nature of the stationary point. In this class you'll learn how to use a nature table to demonstrate what kind of stationary point a function has.
