An Electronic Companion to Precalculus¿

An Electronic Companion to Precalculus uses high-definition graphics and animations to allow you to explore the interconnections between tables of values, points on a graph, and algebraic equations. Interactive exercises teach you how to solve problems using real-life examples, such as determining the shape of the support cables for the Golden Gate bridge or calculating the maximum heart rate for a long-distance runner. Each Electronic Companion is designed to accompany all of the leading course textbooks and includes a print workbook with topic summaries and additional self-testing questions.
