Precalculus (with CD-ROM, Bca/Ilrn Tutorial, and Infotrac)by David Dwyer
Synopses & Reviews
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.
Book News Annotation:
This textbook begins by reviewing foundational issues (real numbers, exponents, algebraic expressions, inequalities, and so on), and then discusses functions and graphing, polynomials, exponential and logarithmic functions, trigonometric functions, trigonometric identities and equations, applications of trigonometry, relations and conic sections, systems of equations and inequalities, and integer functions and probability. A companion CD contains eight hours of video instruction and tutorial exercises. Dwyer and Gruenwald teach at the University of Evansville.

Table of Contents
"The use of graphing utilities is excellent...The integration of the graphing utility throughout the text, not just in the exercises, serves the student well. The authors maintain a balance between the use of technology and the understanding and use of algebraic methods." "The great strength of Dwyer/Gruenwald lies in their superb collection of applications and enrichment problems. These problems are delightfully original, well-planned, and appropriate to the material being presented." "The exercises are the best I've seen in any textbook. The progression from very basic standard problems, to applied problems, and then on to critical thinking, discussion and essay questions, and finally enrichment projects provides a wealth of material to reinforce understanding. The essay questions will nicely supplement efforts to promote writing across the curriculum, and the enrichment projects will be very useful to promote group activities as part of cooperative learning programs." "There is a real effort to connect with the level of the student by stating and developing things in intuitive ways."
