## 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. This Enhanced Edition includes instant access to Enhanced WebAssign®, the most widely-used and reliable homework system. Enhanced WebAssign® presents thousands of problems, links to relevant textbook sections, video examples, problem-specific tutorials, and more, that help students grasp the concepts needed to succeed in this course. As an added bonus, the Start Smart Guide has been bound into this text. This guide contains instructions to help students learn the basics of WebAssign quickly.

Enhanced WebAssign® presents thousands of problems, links to relevant textbook sections, video examples, problem-specific tutorials, and more, that help students grasp the concepts needed to succeed in this course.

- All of the chapters (other than Chapter "P" Prerequisites) are now followed by a "Focus on Modeling" section. Chapter "P" Prerequisites is now the only chapter be followed by a "Problem Solving" section.
- 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 9, Analytic Trigonometry) has been shortened, and the extra material from it, plus some related sections from the Analytic Geometry chapter (previously Chapter 11), have been combined into a new, more logically structured Chapter 9: Polar Coordinates and Vectors.
- This edition includes several new Discovery Projects, for example the Discovery Project in 3.2 on "Relations and Functions," which was added to satisfy those users who asked for some material on relations.

- 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.
- "Focus on Modeling" sections illustrate modeling techniques as well as how 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.
