A-Level Maths OCR B (MEI) (H640)

Be able to use integration by substitution in cases where the process is the reverse of the chain rule (including finding a suitable substitution).

e.g. $(1+2x)^8$, $x(1+x^2)^8$, $xe^{x^2}$, $\dfrac{1}{2x+3}$
Learners can recognise the integral, they need not show all the working for the substitution.
