Dwyer and Gruenwald's PRECALCULUS builds on the same features as their very successful COLLEGE ALGEBRA, Second Edition and COLLEGE ALGEBRA AND TRIGONOMETRY, Second Edition, while adding material to help students look ahead to calculus. The book is organized around a traditional table of contents, and offers a contemporary flavor through the use of the rule of four, modeling, and a strong conceptual orientation. The authors motivate students by using outstanding contemporary applications that address important topical issues, as well as entertaining and illustrative ones. The applications are woven around a carefully paced presentation of algebra and trigonometry topics. A rich variety of exercises further engage and challenge students. In PRECALCULUS, the authors assume that students have access to a variety of graphing calculator models, so generic instruction is provided. Guidelines and keystrokes for specific calculators can be found in the free, text-specific online graphing calculator manual.
