## Description

With the same design and feature sets as leading Precalculus, 8/e, this concise text provides both students and instructors with sound, consistently structured explanations of the mathematical concepts.

PRECALCULUS: A CONCISE is designed to offer a -effective, one-semester alternative to the traditional two-semester precalculus text. It contains the features that have made the Larson/ series a complete for both students and instructors: interesting applications, pedagogically effective design, and innovative technology with an abundance of carefully developed examples with worked-out solutions and exercises.
