## Overview

Precalculus by Lial, Hornsby, Schneider and Daniels channels the experience of master teachers to help you develop the conceptual understanding and analytical skills you need to succeed in mathematics. A systematic approach is used to present each topic and is designed to actively engage you in the learning process. Ample opportunities for review are interspersed within chapters and also found at the end of chapters. The 7th Edition offers a complete suite of materials that supports all classroom types and learners. An expanded Chapter R includes more basic concepts that often challenge students, including a new section on Fractions, Decimals, and Percents.
