Integration Formula Compendium

Recognition Playbook

Before integrating, decide which pattern is trying to reveal itself. Most hard questions collapse after one good recognition step; most wasted time comes from forcing a long method before checking symmetry, a hidden derivative, or a shape-preserving substitution.

Designed as a revision surface, not a theory chapter. Each block gives the usable formula or tactical transform, the trigger that tells you when to reach for it, and a one-line application note so the page stays problem-oriented rather than definition-heavy.
