IAL Pure 3 Integration exam questions

Exam-style questions on integration for Edexcel IAL Pure 3 (WMA13): standard functions, definite integrals and areas under curves. With solutions.

This resource covers the whole of Chapter 7 (Integration) of the Pearson Edexcel International A Level Pure Mathematics 3 course. All questions are original and written in the style of the WMA13 paper — these are not reproduced past paper questions.

What’s covered

Integrating e to the kx, 1/x, sin x and cos x
Integrating expressions that need rewriting first
Definite integrals and exact answers involving e and ln
Areas under and between curves
Using the reverse of the chain rule on simple cases

How to use it

Works as homework, as consolidation across a sequence of lessons, or as revision before the WMA13 paper. Exact answers in terms of e and ln are required throughout the later questions, since a decimal where an exact value was asked for scores nothing.
