Overview

David Cohen, Theodore B. Lee, and David Sklar's PRECALCULUS focuses on the use of a graphical perspective to provide a visual understanding of college algebra and trigonometry. Featuring clear writing and outstanding, graded exercises and applications -- including many examples and exercises involving applications and real-life data -- 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. The authors provide thorough treatment of the graphing calculator; however, the material is arranged to allow instructors to teach the course with as much or as little graphing utility work as they wish.

David Cohen, late of University of California, Los Angeles

David Cohen, a senior lecturer at UCLA, was the original author of the successful, well-respected precalculus series--COLLEGE ALGEBRA, ALGEBRA AND TRIGONOMETRY, PRECALCULUS: A PROBLEMS-ORIENTED APPROACH, and PRECALCULUS: WITH UNIT CIRCLE TRIGONOMETRY.

WebAssign is a flexible and fully customizable online instructional solution that puts powerful tools in the hands of teachers, enabling you to realize your teaching goals and instantly assess individual student performance to help students learn math, not just do online homework.

  • Iteration is covered from numerical, graphical, and algebraic viewpoints.
  • Exercises, praised for their excellence, range in difficulty from simple to more complex and are designated with an "A," "B," or "C" rating.
  • 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.
  • The book features a strong emphasis on graphs and visualization, with numerical, graphical, and algebraic viewpoints tightly linked throughout to help students understand the material.
