Cengage Learning College Algebra: A Contemporary Approach (Available Titles Cengagenow)

Dwyer and Gruenwald's COLLEGE ALGEBRA, SECOND EDITION, is a graphing calculator-dependent text with a contemporary flair. Building upon a traditional table of contents, the authors integrate the best of modern math pedagogy including the rule of four, modeling, and a strong conceptual orientation. The authors motivate students with fresh, current applications that address important topical issues, as well as entertaining and illustrative ones. These applications are woven around a carefully paced presentation of algebra topics. A rich variety of exercises further engage and challenge students. Generic graphing calculator instruction is provided in the text while guidelines and keystrokes for specific calculators can be found in the text-specific manual. Review 1.
