# Precalculus

Paul Sisson

Precalculus starts off with several lessons familiar to students coming from a college algebra course—reviewing topics like linear inequalities, quadratic equations, and inverses of functions—before covering more advanced topics to prepare them for calculus. The text explains elements of trigonometry in detail.
