FP2 (MEI)Calculus 2: Integration using the inverse trigonometric functions

Let Maths take you Further…

Before you start…

- You need to be familiar with the laws of indices (Core 1 chapter 5) and logarithms (Core 2 chapter 11).
- You need to be confident with all the techniques of differentiation and integration in C2 – C4, in particular differentiation using the chain rule, differentiation of trigonometric functions and implicit differentiation (C3 chapter 4), integration by substitution and integration of trigonometric functions (C3 chapter 5) and integration using partial fractions (C4 chapter 10).
- You must also be confident with all the work on Trigonometry covered so far, (C2 chapter 10 and C4 chapter 8).
- When you have finished…You should:
- Recognise integrals of functions of the form
and be able to integrate associated functions by using trigonometrical substitutions (pages 11 – 14).

arctan x

Now that we have these results we can use the chain rule to differentiate composite functions that include inverse trigonometric functions (this was done in the previous tutorial).

This result is in the exam formula book

Consider…for example…

Now you have finished…

- Recognise integrals of functions of the form
and be able to integrate associated functions by using trigonometrical substitutions (see further examples on pages 11 – 14).
