Q: What does H2 Maths Notes (JC 1-2): 5.3) Integration Techniques cover?
A: Substitution, parts, partial fractions, and special integrals for H2 Maths Topic 5.3.

Before you revise
Build a flowchart for integration: recognise the pattern (substitution, parts, partial fractions, trigonometric identities) before diving in. Always write differential substitutions explicitly.

Status: SEAB H2 Mathematics (9758, first exam 2026) syllabus last checked 2026-01-13 (PDF last modified 2024-10-16). Topic 5.3 scope unchanged; Pure Mathematics is assessed in Paper 1 (100 marks) and Paper 2 Section A (40 marks).

Core Formulae

Reverse of differentiation rules (power, exponential, trigonometric, logarithmic).
Integration by substitution: choose $u = g(x)$ to simplify integrand, rewrite $\mathrm{d}x = \dfrac{\mathrm{d}u}{g'(x)}$

Order	Pick this first when
I	an Inverse trigonometric term (e.g. $\operatorname{arctan} x$ ) appears
L	a Logarithmic term (e.g. $\ln x$ ) is present
A	an Algebraic factor (polynomial or rational) remains
T	Trigonometric or hyperbolic functions turn up
E	finally, the Exponential factor $e^{g(x)}$
