College Algebra: A Graphing Approach (with CDROM, Bca/Ilrn Tutorial, and Infotrac)by Gareth Williams
Synopses & ReviewsPublisher Comments:Williams offers a refreshing and innovative approach to college algebra, motivating the topics with a variety of creative applications and thoroughly integrating the graphing calculator. Written in a clear and friendly voice that speaks to students with varying algebra skills, with a rich array of pedagogical devices to support their learning, this text teaches students to look at math from both algebraic and geometric viewpoints. Williams focuses on the underlying concepts, introducing and using the graphing calculator as an integral means, not an end. This new edition is complemented by an outstanding array of innovative supplements (including online tutorials, video lessons on CDROM, and powerful course management and testing resources) that facilitate teaching and enhance learning.
Book News Annotation:This textbook describes methods for analyzing complex numbers, polynomials, logarithmic functions, systems of linear equations, matrices and arithmetic sequences, and confirms the results of some examples with a calculator graph. The second edition adds new applications. The CDROM contains eight hours of video instruction.
Annotation ©2004 Book News, Inc., Portland, OR (booknews.com) About the AuthorGareth Williams received his B. Sc. and Ph.D. from the University of Wales. He has taught at the University of Florida, the University of Denver, and most recently, at Stetson University (DeLand, FL), where he was honored with the McInery Award for Teaching Excellence. His research interests include the role of technology in mathematics education, linear algebra, relativity, applied mathematics, and mathematical modeling. He is also the author of LINEAR ALGEBRA WITH APPLICATIONS, Fourth Edition (Jones and Bartlett, 2001), computer software including THE LINEAR ALGEBRA TOOLBOX FOR MATLAB and MATHEMATICA WORKBOOK ON LINEAR ALGEBRA, and numerous articles in refereed journals. Williams is also an active member of the Mathematics Association of America.
