## Overview

This best selling author team explains concepts simply and clearly, without glossing over difficult points. Problem solving and mathematical modeling are introduced early and reinforced throughout, so that when students finish the course, they have a solid foundation in the principles of mathematical thinking. This comprehensive, evenly paced book provides complete coverage of the function concept and integrates substantial graphing calculator materials that help students develop insight into mathematical ideas. The authors' attention to detail and clarity, as in James Stewart's market-leading Calculus text, is what makes this text the market leader.

- All of the chapters (other than Chapter 1) are now followed by a "Focus on Modeling" section. Chapter 1 is now the only chapter to be followed by a "Problem Solving" section.
- This edition includes several new Discovery Projects, for example the Discovery Project in 2.2 on "Relations and Functions," which was added to satisfy those users who asked for some material on relations.
- More than 20% of the exercises are new, including many more application exercises. Many others have been updated and revised.
- Each chapter now begins with a one-page "Chapter Overview" to introduce the ideas of the chapter and indicate how they can be applied to the real world.
- There are six new "Focus on Modeling" sections, containing high-interest applications ranging from surveying to architecture.
- Each exercise section now contains a special group heading for "Applications" exercises, to give these more prominence and to make them easier to assign. Each such exercise has a title to clarify its purpose at a glance.
- One of the very long chapters (Chapter 7, Analytic Trigonometry) has been shortened, and the extra material from it, plus some related sections from the Analytic Geometry chapter (previously Chapter 9), have been combined into a new, more logically structured Chapter 8: Polar Coordinates and Vectors.
- Based on reviewer feedback, the chapter on probability (formerly Chapter 11) was deleted. For those who want to use this chapter, it is available as a student resource on the Book Companion Website for the text (at www.brookscole.com/math).

- "Focus On Modeling" sections illustrate modeling techniques as well as how precalculus mathematics can be applied to model real-life situations. These sections, as well as others, are devoted to teaching students how to create their own mathematical models, rather than using prefabricated formulas.
- Real-world applications from engineering, physics, chemistry, business, biology, environmental studies, and other fields demonstrate how mathematics is used to model real-life situations.
- The authors introduce the graphing calculator early, so it can be used to graph and solve equations prior to the introduction of functions. Material that deals with graphing devices is labeled with an icon so that those who prefer not to use the graphing calculator can easily skip this material.
- The chapters on trigonometry have been written so professors can begin with either the right triangle approach or the unit circle approach.
- Each approach to trigonometry is accompanied by the applications appropriate for that approach, clarifying the reason for different approaches to trigonometry.
- "Mathematics In The Modern World" vignettes show that mathematics is a living science crucial to the scientific and technological progress of recent times, as well as to the social, behavioral, and life sciences.
- Discovery - Discussion problems at the end of every section encourage conceptual, critical thinking, and writing skills.
- Special projects are included in each chapter to engage students and make them active learners by having them work (perhaps in groups) on extended projects that give a feeling of substantial accomplishment when completed.
- Review Sections and Chapter Tests at the end of each chapter help students gauge their learning progress. Brief answers to the odd-numbered exercises in each section and to all questions in the Chapter Tests are given at the back of the book.
- This edition is fully supported with iLrn�. Providing instructors and students with unsurpassed control, variety, and all-in-one utility, iLrn is a powerful and fully integrated teaching and learning system. iLrn ties together five fundamental learning activities: diagnostics, tutorials, homework, quizzing, and testing.
