Mathematical reform is the driving force behind the organization and development of this new text. The use of technology,primarily graphing utilities, is assumed throughout the text. The development of each topic proceeds from the concrete to the abstract and takes full advantage of technology,wherever appropriate. The first major objective of this book is to encourage students to investigate mathematical ideas and processes graphically and numerically,as well as algebraically.

The Barnett, Ziegler, Byleen, and Sobecki College Algebra series is designed to be user friendly and to maximize student comprehension by emphasizing computational skills, ideas, and problem solving as opposed to mathematical theory. Suitable for either one or two semester college algebra with trigonometry or precalculus courses, Precalculus introduces a unit circle to trigonometry and includes a chapter on limits to provide students with a solid foundation for concepts.
