December 30, 2008 11:00 M91-for-the-student Sheet number Page number ii cyan magenta yellow black FOR THE STUDENT Calculus provides a way of viewing and analyzing the physical world As with all mathematics courses, calculus involves equations and formulas However, if you successfully learn to use all the formulas and solve all of the problems in the text but not master the underlying ideas, you will have missed the most important part of calculus If you master these ideas, you will have a widely applicable tool that goes far beyond textbook exercises Before starting your studies, you may find it helpful to leaf through this text to get a general feeling for its different parts: ■ The opening page of each chapter gives you an overview of what that chapter is about, and the opening page of each section within a chapter gives you an overview of what that section is about To help you locate specific information, sections are subdivided into topics that are marked with a box like this ■ Each section ends with a set of exercises The answers to most odd-numbered exercises appear in the back of the book If you find that your answer to an exercise does not match that in the back of the book, not assume immediately that yours is incorrect—there may be more than one way example, if your answer is √ to express the answer For √ 2/2 and the text answer is 1/ , then both are correct since your answer can be obtained by “rationalizing” the text answer In general, if your answer does not match that in the text, then your best first step is to look for an algebraic manipulation or a trigonometric identity that might help you determine if the two answers are equivalent If the answer is in the form of a decimal approximation, then your answer might differ from that in the text because of a difference in the number of decimal places used in the computations ■ The section exercises include regular exercises and four special categories: Quick Check, Focus on Concepts, True/False, and Writing • theorem in the text that shows the statement to be true or by finding a particular example in which the statement is not true Writing exercises are intended to test your ability to explain mathematical ideas in words rather than relying solely on numbers and symbols All exercises requiring writing should be answered in complete, correctly punctuated logical sentences—not with fragmented phrases and formulas ■ Each chapter ends with two additional sets of exercises: Chapter Review Exercises, which, as the name suggests, is a select set of exercises that provide a review of the main concepts and techniques in the chapter, and Making Connections, in which exercises require you to draw on and combine various ideas developed throughout the chapter ■ Your instructor may choose to incorporate technology in your calculus course Exercises whose solution involves the use of some kind of technology are tagged with icons to alert you and your instructor Those exercises tagged with the icon require graphing technology—either a graphing calculator or a computer program that can graph equations Those exercises tagged with the icon C require a computer algebra system (CAS) such as Mathematica, Maple, or available on some graphing calculators ■ At the end of the text you will find a set of four appen- dices covering various topics such as a detailed review of trigonometry and graphing techniques using technology Inside the front and back covers of the text you will find endpapers that contain useful formulas ■ The ideas in this text were created by real people with in- teresting personalities and backgrounds Pictures and biographical sketches of many of these people appear throughout the book ■ Notes in the margin are intended to clarify or comment on • The Quick Check exercises are intended to give you important points in the text quick feedback on whether you understand the key ideas in the section; they involve relatively little computation, and have answers provided at the end of the exercise set A Word of Encouragement • The Focus on Concepts exercises, as their name sug• gests, key in on the main ideas in the section True/False exercises focus on key ideas in a different way You must decide whether the statement is true in all possible circumstances, in which case you would declare it to be “true,” or whether there are some circumstances in which it is not true, in which case you would declare it to be “false.” In each such exercise you are asked to “Explain your answer.” You might this by noting a As you work your way through this text you will find some ideas that you understand immediately, some that you don’t understand until you have read them several times, and others that you not seem to understand, even after several readings Do not become discouraged—some ideas are intrinsically difficult and take time to “percolate.” You may well find that a hard idea becomes clear later when you least expect it Wiley Web Site for this Text www.wiley.com/college/anton Achieve Positive Learning Outcomes W ileyPLUS combines robust course management tools with interactive teaching and learning resources all in one easy-to-use system It has helped over half a million students and instructors achieve positive learning outcomes in their courses WileyPLUS contains everything you and your students need— and nothing more, including: The entire textbook online—with dynamic links from homework to relevant sections Students can use the online text and save up to half the cost of buying a new printed book Automated assigning & grading of homework & quizzes An interactive variety of ways to teach and learn the material Instant feedback and help for students… available 24/7 “WileyPLUS helped me become more prepared There were more resources available using WileyPLUS than just using a regular [printed] textbook, which helped out significantly Very helpful and very easy to use.” — Student Victoria Cazorla, Dutchess County Community College See and try WileyPLUS in action!

ninth edition of Calculus maintains those aspects of previous editions that have led to the series’ success—we continue to strive for student comprehension without sacrificing mathematical accuracy, and the exercise sets are carefully constructed to avoid unhappy surprises that can derail a calculus class However, this edition also has many new features that we hope will attract new users and also motivate past users to take a fresh look at our work We had two main goals for this edition: • To make those adjustments to the order and content that would align the text more precisely with the most widely followed calculus outlines • To add new elements to the text that would provide a wider range of teaching and learning tools All of the changes were carefully reviewed by an advisory committee of outstanding teachers comprised of both users and nonusers of the previous edition The charge of this committee was to ensure that all changes did not alter those aspects of the text that attracted users of the eighth edition and at the same time provide freshness to the new edition that would attract new users Some of the more substantive changes are described below NEW FEATURES IN THIS EDITION New Elements in the Exercises We added new true/false exercises, new writing exercises, and new exercise types that were requested by reviewers of the eighth edition Making Connections We added this new element to the end of each chapter A Making Connections exercise synthesizes concepts drawn across multiple sections of its chapter rather than using ideas from a single section as is expected of a regular or review exercise Reorganization of Review Material The precalculus review material that was in Chapter of the eighth edition forms Chapter of the ninth edition The body of material in Chapter of the eighth edition that is not generally regarded as precalculus review was moved to appropriate sections of the text in this edition Thus, Chapter focuses exclusively on those preliminary topics that students need to start the calculus course Parametric Equations Reorganized In the eighth edition, parametric equations were introduced in the first chapter and picked up again later in the text Many instructors asked that we return to the traditional organization, and we have done so; the material on parametric equations is now first introduced and then discussed in detail in Section 10.1 (Parametric Curves) However, to support those instructors who want to continue the eighth edition path of giving an early exposure to parametric curves, we have provided Web materials (Web Appendix I) as well as self-contained exercise sets on the topic in Section 6.4 (Length of a Plane Curve) and Section 6.5 (Area of a Surface of Revolution) vii January 9, 2009 11:08 viii m91-fm-et Sheet number Page number viii cyan magenta yellow black Preface Also, Section 14.4 (Surface Area; Parametric Surfaces) has been reorganized so surfaces of the form z = f (x, y) are discussed before surfaces defined parametrically Differential Equations Reorganized We reordered and revised the chapter on differential equations so that instructors who cover only separable equations can so without a forced diversion into general first-order equations and other unrelated topics This chapter can be skipped entirely by those who not cover differential equations at all in calculus New 2D Discussion of Centroids and Center of Gravity In the eighth edition and earlier, centroids and center of gravity were covered only in three dimensions In this edition we added a new section on that topic in Chapter (Applications of the Definite Integral), so centroids and center of gravity can now be studied in two dimensions, as is common in many calculus courses Related Rates and Local Linearity Reorganized The sections on related rates and local linearity were moved to follow the sections on implicit differentiation and logarithmic, exponential, and inverse trigonometric functions, thereby making a richer variety of techniques and functions available to study related rates and local linearity Rectilinear Motion Reorganized The more technical aspects of rectilinear motion that were discussed in the introductory discussion of derivatives in the eighth edition have been deferred so as not to distract from the primary task of developing the notion of the derivative This also provides a less fragmented development of rectilinear motion Other Reorganization The section Graphing Functions Using Calculators and Computer Algebra Systems, which appeared in the text body of the eighth edition, is now a text appendix (Appendix A), and the sections Mathematical Models and Second-Order Linear Homogeneous Differential Equations are now posted on the Web site that supports the text OTHER FEATURES Flexibility This edition has a built-in flexibility that is designed to serve a broad spectrum of calculus philosophies—from traditional to “reform.” Technology can be emphasized or not, and the order of many topics can be permuted freely to accommodate each instructor’s specific needs Rigor The challenge of writing a good calculus book is to strike the right balance between rigor and clarity Our goal is to present precise mathematics to the fullest extent possible in an introductory treatment Where clarity and rigor conflict, we choose clarity; however, we believe it to be important that the student understand the difference between a careful proof and an informal argument, so we have informed the reader when the arguments being presented are informal or motivational Theory involving -δ arguments appears in a separate section so that it can be covered or not, as preferred by the instructor Rule of Four The “rule of four” refers to presenting concepts from the verbal, algebraic, visual, and numerical points of view In keeping with current pedagogical philosophy, we used this approach whenever appropriate Visualization This edition makes extensive use of modern computer graphics to clarify concepts and to develop the student’s ability to visualize mathematical objects, particularly January 8, 2009 13:25 m91-et-index-10-12 Sheet number 17 Page number
