Overview

Do your students attempt to memorize facts and mimic examples to make it through algebra? James Stewart, author of the worldwide, best-selling calculus texts, saw this scenario time and again in his classes. So, along with longtime coauthors Lothar Redlin and Saleem Watson, he wrote COLLEGE ALGEBRA specifically to help students learn to think mathematically and to develop genuine problem-solving skills. Comprehensive and evenly-paced, the text has helped hundreds of thousands of students. Incorporating technology, real-world applications, and additional useful pedagogy, the Seventh Edition promises to help more students than ever build conceptual understanding and a core of fundamental skills.

James Stewart, McMaster University

The late James Stewart received his M.S. from Stanford University and his Ph.D. from the University of Toronto. He did research at the University of London and was influenced by the famous mathematician George Polya at Stanford University. Stewart was most recently Professor of Mathematics at McMaster University, and his research field was harmonic analysis. Stewart was the author of a best-selling calculus textbook series published by Cengage Learning, including CALCULUS, CALCULUS: EARLY TRANSCENDENTALS, and CALCULUS: CONCEPTS AND CONTEXTS, as well as a series of precalculus texts.

Lothar Redlin, Pennsylvania State University, Abington Campus

Lothar Redlin grew up on Vancouver Island, received a Bachelor of Science degree from the University of Victoria, and a Ph.D. from McMaster University in 1978. He subsequently did research and taught at the University of Washington, the University of Waterloo, and California State University, Long Beach. He is currently Professor of Mathematics at The Pennsylvania State University, Abington Campus. His research field is topology.

Saleem Watson, California State University, Long Beach

Saleem Watson received his Bachelor of Science degree from Andrews University in Michigan. He did graduate studies at Dalhousie University and McMaster University, where he received his Ph.D. in 1978. He subsequently did research at the Mathematics Institute of the University of Warsaw in Poland. He also taught at The Pennsylvania State University. He is currently Professor of Mathematics at California State University, Long Beach. His research field is functional analysis.
  • Exercises - New Skills Plus exercises in most sections contain more challenging exercises that require students to extend and synthesize concepts. Additionally, more than 20% of the exercises are new, and groups of exercises now have headings that identify the type of exercise.
  • Review Material - The review material at the end of each chapter now includes a Concept Check which provides a step-by-step review of all the main concepts and applications of the chapter. Answers to the Concept Check questions are in tear-out sheets at the back of the book.
  • Discovery Projects - References to Discovery Projects, including brief descriptions of the content of each project, are located in boxes where appropriate in each chapter. These boxes highlight the applications of college algebra in many different real-world contexts. The projects are located at the book companion website www.stewartmath.com.
  • Chapter P Prerequisites - This chapter now includes Section P.9 "Modeling with Equations." This section extends the theme of the introductory section P.1 "Modeling the Real World with Algebra" on the usefulness of algebra in solving real-world problems.
  • Chapter 1 Coordinates and Graphs - This chapter has been reorganized. The chapter now begins with the coordinate plane and graphs of equations (including circles and lines), followed by sections on solving equations algebraically, and then a section on solving equations graphically. This last section shows the connections between graphs and the solutions of equations.
  • Chapter 2 Functions - This chapter now includes the new Section 2.5, "Linear Functions and Models." This section highlights the connection between the slope of a line and the rate of change of a linear function. These two interpretations of slope help prepare students for the concept of the derivative in calculus.
  • Chapter 3 Polynomial and Rational Functions - This chapter now includes the new Section 3.7, "Solving Polynomial and Rational Inequalities Graphically." Section 3.6, "Rational Functions," has a new subsection on rational functions with "holes." The sections on complex numbers and on variation have been moved to Chapter 1.
  • Chapter 4 Exponential and Logarithmic Functions - The chapter now includes two sections on the applications of these functions. Section 4.7, "Modeling with Exponential Functions," focuses on modeling growth and decay, Newton's Law of Cooling, and other such applications. Section 4.8, "Logarithmic Scales," covers the concept of a logarithmic scale with applications involving the pH, Richter, and decibel scales.
  • Chapter 5 Systems of Equations and Inequalities - The material on systems of inequalities has been rewritten to emphasize the steps used in graphing the solution of a system of inequalities.
  • The new Get Ready feature at the beginning of a section lets students know which previous sections they need to have mastered before starting the section.
  • Concept exercises, in addition to drill/skill exercises, vary from easy to difficult and help ensure that students are truly grasping the algebraic theories.
  • Practice What You've Learned features at the end of each example directs students to a similar problem in the exercises, allowing them to immediately reinforce the concept just covered.
  • Cumulative Reviews appear after select groups of chapters and help students gauge their progress and gain experience in taking tests that cover a broad range of concepts and skills.
  • Enhanced WebAssign allows you to assign, collect, grade, and record homework assignments online, minimizing workload and streamlining the grading process. It also gives students the ability to stay organized with assignments and have up-to-date grade information.
  • Many real-world applications show students how mathematics is used to model in fields such as engineering, physics, chemistry, business, and biology and help them relate the concepts they're studying to the world around them.
  • Focus on Modeling sections show how algebra can be applied to model real-life situations.
  • Optional, yet complete, technology applications for graphing calculators and computers appear throughout the text, giving you the flexibility to teach the course the way you want.
