Precalculus: Raymond A. Barnett, Michael R. Ziegler, Karl E. Byleen.

This third edition has a new open format and expanded graphics which enforce concepts. Through an informal, active writing style and the use of numerous pedagogical aids, such as examples with matched problems, annotations, think boxes, chapter summaries and cumulative reviews, the text guides students of varied disciplines to success in college algebra and trigonometry. In response to the increasing popularity of graphing calculators in mathematics, numerous exercises that exploit the capabilities of these calculators have been incorporated into this edition. There is a new chapter on probability; other new features include illustrative examples, new and varied problems, and new and updated applications.
