In this unit we explain how these can be differentiated using implicit differentiation. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that they become second nature.
This procedure is known as implicit differentiation and we will make it a little simpler to find by skipping all of the substitutions. Instead of rewriting y as f(x) we will just find the derivative of y and multiply it by dx dy to represent the derivative of y as a function of x.
Implicit differentiation was already crucial to find the derivative of inverse functions. We will review this here because this will give us handy tools for integration.
Part C: Implicit Differentiation Method 1 – Step by Step using the Chain Rule Since implicit functions are given in terms of , deriving with respect to involves the application of the chain rule. Example 2: Given the function, + , find . Step 1: Multiple both sides of the function by ( + ) ( ) ( ) + ( ) ( )
