solves a great problem but there is a grain of discovery in the solution of any problem Your problem may be modest; but if it challenges your curiosity and brings into play your inventive faculties, and if you solve it by your own means, you may experience the tension and enjoy the triumph of discovery GEORGE POLYA The art of teaching, Mark Van Doren said, is the art of assisting discovery I have tried to write a book that assists students in discovering calculus—both for its practical power and its surprising beauty In this edition, as in the first six editions, I aim to convey to the student a sense of the utility of calculus and develop technical competence, but I also strive to give some appreciation for the intrinsic beauty of the subject Newton undoubtedly experienced a sense of triumph when he made his great discoveries I want students to share some of that excitement The emphasis is on understanding concepts I think that nearly everybody agrees that this should be the primary goal of calculus instruction In fact, the impetus for the current calculus reform movement came from the Tulane Conference in 1986, which formulated as their first recommendation: Focus on conceptual understanding I have tried to implement this goal through the Rule of Three: “Topics should be presented geometrically, numerically, and algebraically.” Visualization, numerical and graphical experimentation, and other approaches have changed how we teach conceptual reasoning in fundamental ways The Rule of Three has been expanded to become the Rule of Four by emphasizing the verbal, or descriptive, point of view as well In writing the seventh edition my premise has been that it is possible to achieve conceptual understanding and still retain the best traditions of traditional calculus The book contains elements of reform, but within the context of a traditional curriculum Alternative Versions I have written several other calculus textbooks that might be preferable for some instructors Most of them also come in single variable and multivariable versions ■ Calculus, Seventh Edition, Hybrid Version, is similar to the present textbook in content and coverage except that all end-of-section exercises are available only in Enhanced WebAssign The printed text includes all end-of-chapter review material ■ Calculus: Early Transcendentals, Seventh Edition, is similar to the present textbook except that the exponential, logarithmic, and inverse trigonometric functions are covered in the first semester vii Copyright 2010 Cengage Learning All

to Calculus: Early Transcendentals, Seventh Edition, in content and coverage except that all end-of-section exercises are available only in Enhanced WebAssign The printed text includes all end-of-chapter review material ■ Essential Calculus is a much briefer book (800 pages), though it contains almost all of the topics in Calculus, Seventh Edition The relative brevity is achieved through briefer exposition of some topics and putting some features on the website ■ Essential Calculus: Early Transcendentals resembles Essential Calculus, but the exponential, logarithmic, and inverse trigonometric functions are covered in Chapter ■ Calculus: Concepts and Contexts, Fourth Edition, emphasizes conceptual understanding even more strongly than this book The coverage of topics is not encyclopedic and the material on transcendental functions and on parametric equations is woven throughout the book instead of being treated in separate chapters ■ Calculus: Early Vectors introduces vectors and vector functions in the first semester and integrates them throughout the book It is suitable for students taking Engineering and Physics courses concurrently with calculus ■ Brief Applied Calculus is intended for students in business, the social sciences, and the life sciences What’s New in the Seventh Edition? The changes have resulted from talking with my colleagues and students at the University of Toronto and from reading journals, as well as suggestions from users and reviewers Here are some of the many improvements that I’ve incorporated into this edition: ■ Some material has been rewritten for greater clarity or for better motivation See, for instance, the introduction to series on page 727 and the motivation for the cross product on page 832 ■ New examples have been added (see Example on page 1045 for instance), and the solutions to some of the existing examples have been amplified ■ The art program has been revamped: New figures have been incorporated and a substantial percentage of the existing figures have been redrawn ■ The data in examples and exercises have been updated to be more timely ■ One new project has been added: Families of Polar Curves (page 688) exhibits the fascinating shapes of polar curves and how they evolve within a family ■ The section on the surface area of the graph of a function of two variables has been restored as Section 15.6 for the convenience of instructors who like to teach it after double integrals, though the full treatment of surface area remains in Chapter 16 ■ I continue to seek out examples of how calculus applies to so many aspects of the real world On page 933 you will see beautiful images of the earth’s magnetic field strength and its second vertical derivative as calculated from Laplace’s equation I thank Roger Watson for bringing to my attention how this is used in geophysics and mineral exploration ■ More than 25% of the exercises are new Here are some of my favorites: 11.2.49–50, 11.10.71–72, 12.1.44, 12.4.43–44, 12.5.80, 14.6.59–60, 15.8.42, and Problems 4, 5, and on pages 861–62 Copyright 2010 Cengage Learning All Rights Reserved May not be copied, scanned, or duplicated, in whole or in part Due to electronic rights, some third party content may be suppressed from the eBook and/or eChapter(s) Editorial review has deemed that any suppressed content does not materially affect the overall learning experience Cengage Learning reserves the right to remove additional content at any time if subsequent rights restrictions require it ... current editions, and alternate formats, please visit www .cengage. com/highered to search by ISBN#, author, title, or keyword for materials in your areas of interest Copyright 2010 Cengage Learning. ..
