PRECALCULUS, Fourth Edition focuses on teaching the essentials of what a student needs to fulfill their precalculus requirement and to fully prepare them to succeed in calculus. It provides students with an integrated review of algebra and trigonometry while focusing on essential calculus concepts. Faires and DeFranza prepare students for calculus by providing a solid grounding in analysis and graphing, tools necessary to make a successful transition to calculus. This streamlined text provides all the mathematics that students need--it doesn't bog them down in review, or overwhelm them with too much, too soon. The authors are careful to keep this book, unlike many of the precalculus books on the market, at a length that can be covered in one term.J. Douglas Faires is the author of 'Precalculus', published 2006 under ISBN 9780495113485 and ISBN 0495113484.
