Precalculus, Enhanced Edition
By David Cohen, Theodore B. Lee, David Sklar
About your course materials
Written by David Cohen and co-authors Theodore B. Lee and David Sklar, PRECALCULUS, Seventh Edition, focuses on the use of a graphical perspective to provide a visual understanding of college algebra and trigonometry. Cohen’s texts are known for their clear writing style and outstanding, graded exercises and applications, including many examples and exercises involving applications and real-life data. Combining material from two other Cohen texts, the Seventh Edition accommodates the introduction of trigonometry with either a right-triangle approach or a unit-circle approach. Graphs, visualization of data, and functions are introduced and emphasized early on to aid student understanding. Although the text provides thorough treatment of the graphing calculator, the material is arranged to allow instructors to teach the course with as much or as little graphing utility work as they wish.

Thorough treatment of the role of the graphing utility is carefully integrated throughout the text. Graphing utility exercises are identified in the exercise sets with an icon. Reviewers have praised this book’s thoughtful approach to the optional use of technology, lauding the way it covers the realistic use of modern technologies while providing a solid foundation in algebraic concepts.
"Writing Mathematics" sections and "Projects" (the latter now referenced in the book and available online) give students opportunities to discuss, explore, learn, and write about mathematics.
Functions, introduced in Chapter 3, are presented at length using algebraic, verbal, tabular, and graphical forms. Functions as models are introduced and used in examples and exercises.
The "Graphical Perspective" feature uses graphs to supplement the text discussion and encourage students to produce their own pictures of a graph.
