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 CD-ROM, and powerful course management and testing resources) that facilitate teaching and enhance learning.
