College Algebra & Trigonometry 2ND Editionby David Dwyer
Synopses & ReviewsPlease note that used books may not include additional media (study guides, CDs, DVDs, solutions manuals, etc.) as described in the publisher comments.
Dwyer and Gruenwald's COLLEGE ALGEBRA AND TRIGONOMETRY, 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 and trigonometry 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.
Book News Annotation:
To counter many students' attitude of mathematics being a "soulless game of symbolic manipulation," Dwyer and Gruenwald (U. of Evansville) emphasize that mathematical models underpin decisions about vital phenomena such as the spread of disease and global warming. Chapters on such topics as the fundamentals, functions and their graphs, and new sections covering parametric equations and rotation of conic sections open with stimulating critical thinking questions such as: "How fast is the human population expanding?" and "How do parabolas help us search for extraterrestrial life?" Learning aids include ample graphics, warning boxes about common pitfalls, mastery checklists, exercises, and applied problems geared to the use of a graphing calculator.
