Precalculus: Graphs and Models, A Right Triangle Approach (6e)

A college precalculus textbook by Bittinger, Beecher, Ellenbogen, and Penna in the Graphs and Models series, using a right-triangle approach to introduce trigonometry. Covers a basic-algebra review, graphs and functions, polynomial and rational functions, exponential and logarithmic functions, the trig functions, trig identities/inverses/equations, applications of trigonometry, systems of equations and matrices, analytic geometry topics, and sequences/series/combinatorics. Emphasizes graphing-utility integration and modeling throughout.
