Year 13/A2 Pure Chapter 11.4 (Integration)

This video covers what is known as the "reverse chain rule" for integration, but I tend to teach this topic in terms of u - substitutions as spotting integrals "by inspection" isn't always easy - and certainly harder to spot if you are relatively new to integration.

This lesson is meant as preparation for Exercise 11D, page 302 of the Pearson Edexcel Pure Mathematics Year 2/A2 Textbook.
