## Description

**This edition features the exact same content as the traditional text in a convenient, three-hole- punched, loose-leaf version. Books à la Carte also offer a great value—this format costs significantly less than a new textbook.**

**Precalculus: Concepts Through Functions, A Right Triangle Approach to Trigonometry, Second Edition** embodies Sullivan/Sullivan’s hallmarks–accuracy, precision, depth, strong student support, and abundant exercises–while exposing readers to functions in the first chapter. To ensure that students master basic skills and develop the conceptual understanding they need for the course, this text focuses on the fundamentals: *preparing *for class, *practicing *their homework, and *reviewing* the concepts. After using this book, students will have a solid understanding of algebra and functions so that they are prepared for subsequent courses, such as finite mathematics, business mathematics, and engineering calculus.** **
