College Algebra

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.

NOTE: This title is also available in WebAssign with Corequisite Support that provides the flexibility to match any corequisite implementation model and empowers you to deliver high quality content at the right time for your students at an affordable price.

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.

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.
