C. Henry Edwards is emeritus professor of mathematics at the University of Georgia. He earned his Ph.D. at the University of Tennessee in 1960, and recently retired after 40 years of classroom teaching (including calculus or differential equations almost every term) at the universities of Tennessee, Wisconsin, and Georgia, with a brief interlude at the Institute for Advanced Study (Princeton) as an Alfred P. Sloan Research Fellow. He has received numerous teaching awards, including the University of Georgia's honoratus medal in 1983 (for sustained excellence in honors teaching), its Josiah Meigs award in 1991 (the institution's highest award for teaching), and the 1997 statewide Georgia Regents award for research university faculty teaching excellence. His scholarly career has ranged from research and dissertation direction in topology to the history of mathematics to computing and technology in the teaching and applications of mathematics. In addition to being author or coauthor of calculus, advanced calculus, linear algebra, and differential equations textbooks, he is wellknown to calculus instructors as author of The Historical Development of the Calculus (SpringerVerlag, 1979). During the 1990s he served as a principal investigator on three NSFsupported projects: (1) A school mathematics project including Maple for beginning algebra students, (2) A CalculuswithMathematica program, and (3) A MATLABbased computer lab project for numerical analysis and differential equations students.
David E. Penney, University of Georgia, completed his Ph.D. at Tulane University in 1965 (under the direction of Prof. L. Bruce Treybig) while teaching at the University of New Orleans. Earlier he had worked in experimental biophysics at Tulane University and the Veteran's Administration Hospital in New Orleans under the direction of Robert Dixon McAfee, where Dr. McAfee's research team's primary focus was on the active transport of sodium ions by biological membranes. Penney's primary contribution here was the development of a mathematical model (using simultaneous ordinary differential equations) for the metabolic phenomena regulating such transport, with potential future applications in kidney physiology, management of hypertension, and treatment of congestive heart failure. He also designed and constructed servomechanisms for the accurate monitoring of ion transport, a phenomenon involving the measurement of potentials in microvolts at impedances of millions of megohms. Penney began teaching calculus at Tulane in 1957 and taught that course almost every term with enthusiasm and distinction until his retirement at the end of the last millennium. During his tenure at the University of Georgia he received numerous Universitywide teaching awards as well as directing several doctoral dissertations and seven undergraduate research projects. He is the author of research papers in number theory and topology and is the author or coauthor of textbooks on calculus, computer programming, differential equations, linear algebra, and liberal arts mathematics.
Read an Excerpt
Contemporary calculus instructors and students face traditional challenges as well as new ones that result from changes in the role and practice of mathematics by scientists and engineers in the world at large. As a consequence, this sixth edition of our calculus textbook is its most extensive revision since the first edition appeared in 1982.
Two chapters of the fifth edition have been combined in a single more tightly organized one. An entirely new chapter now appears in the table of contents, and most of the remaining chapters have been extensively rewritten. About 125 of the book's over 750 worked examples are new for this edition and the 1825 figures in the text include 225 new computergenerated graphics. About 600 of its over 7000 problems are new, and these are augmented by 320 new conceptual discussion questions that now precede the problem sets. Moreover, 1050 new true/false questions are included in the Study Guides on the new CDROM that accompanies this edition. In summary, almost 2000 of these 8400plus problems and questions are new, and the text discussion and explanations have undergone corresponding alteration and improvement.
PRINCIPAL NEW FEATURES
The current revision of the text features
The new chapter on differential equations now appears immediately after Chapter 8 on techniques of integration. It includes both direction fields and Eider's method together with the more elementary symbolic methods (which exploit techniques from Chapter 8) and interesting applications of both first and secondorder equations. Chapter 11 (Infinite Series) now ends with a new section on power series solutions of differential equations, thus bringing full circle a unifying focus of secondsemester calculus on elementary differential equations.
NEW LEARNING RESOURCES
Conceptual Discussion Questions: The set of problems that concludes each section is now preceded by a brief Concepts: Questions and Discussion set consisting of several openended conceptual questions that can be used for either individual study or classroom discussion.
The Text CDROM: The content of the new CDROM that accompanies this text is fully integrated with the textbook material, and is designed specifically for use handinhand with study of the book itself. This CDROM features the following resources to support learning and teaching:
PH Grade Assist (Computerized Homework Grading System)About 2000 of the textbook problems are incorporated in an automated grading system that is now available. Each problem solution in the system is structured algorithmically so that students can work in a computer lab setting to submit homework assignments for automatic grading. (There is a small annual fee per participating student.)
New Solutions Manuals: The entirely new 1810page Instructor's Solutions Manual (available in three volumes) includes a detailed solution for every problem in the book. These solutions were written exclusively by the authors and have been checked independently by others.
The entirely new 930page Student Solutions Manual (available in two volumes) includes a detailed solution for every oddnumbered problem in the text. The answers (alone) to most of these oddnumbered problems are included in the answers section at the back of this book.
New Technology manuals: Each of the following manuals is available shrinkwrapped with any version of the text for half the normal price of the manual (all of which are inexpensive):
In preparing this edition, we have taken advantage of many valuable comments and suggestions from users of the first five editions. This revision was so pervasive that the individual changes are too numerous to be detailed in a preface, but the following paragraphs summarize those that may be of widest interest.
New Problems—Most of the 600 new problems lie in the intermediate range of difficulty, neither highly theoretical nor computationally routine. Many of them have a new technology flavor, suggesting (if not requiring) the use of technology ranging from a graphing calculator to a computer algebra system.
Discussion Questions and Study Guides—We hope the 320 conceptual discussion questions and 1050 true/false studyguide questions constitute a useful addition to the traditional fare of student exercises and problems. The True/False Study Guide for each section provides a focus on the key ideas of the section, with the single goal of motivating guided student reading of the section.
Examples and Explanations—About onesixth of the book's worked examples are either new or significantly revised, together with a similar percentage of the text discussion and explanations. Additional computational detail has been inserted in worked examples where students have experienced difficulty, together with additional sentences and paragraphs in similar spots in text discussions.
Project Material—Many of the text's 33 projects are new for this edition. These appear following the problem sets at the ends of key sections throughout the text. Most (but not all) of these projects employ some aspect of modern computational technology to illustrate the principal ideas of the preceding section, and many contain additional problems intended for solution with the use of a graphing calculator or computer algebra system. Where appropriate, project discussions are significantly expanded in the CDROM versions of the projects.
Historical Material—Historical and biographical chapter openings offer students a sense of the development of our subject by real human beings. Indeed, our exposition of calculus frequently reflects the historical development of the subject—from ancient times to the ages of Newton and Leibniz and Euler to our own era of new computational power and technology.
TEXT ORGANIZATION
Introductory Chapters—Instead of a routine review of precalculus topics, Chapter 1 concentrates specifically on functions and graphs for use in mathematical modeling. It includes a section cataloging informally the elementary transcendental functions of calculus, as background to their more formal treatment using calculus itself. Chapter 1 concludes with a section addressing the question "What is calculus?" Chapter 2 on limits begins with a section on tangent lines to motivate the official introduction of limits in Section 2.2. Trigonometric limits are treated throughout Chapter 2 in order to encourage a richer and more visual introduction to the limit concept.
Differentiation Chapters—The sequence of topics in Chapters 3 and 4 differs a bit from the most traditional order. We attempt to build student confidence by introducing topics more nearly in order of increasing difficulty. The chain rule appears quite early (in Section 3.3) and we cover the basic techniques for differentiating algebraic functions before discussing maxima and minima in Sections 3.5 and 3.6 (in order to illustrate early some significant applications of the derivative). Section 3.7 treats the derivatives of all six trigonometric functions. The authors' fondness for Newton's method (Section 3.8) will be apparent.
The mean value theorem and its applications are deferred to Chapter 4 (following implicit differentiation and related rates in Section 4.1, and differentials and linear approximation in Section 4.2). In addition, a dominant theme of Chapter 4 is the use of calculus both to construct graphs of functions and to explain and interpret graphs that have been constructed by a calculator or computer. This theme is developed in Sections 4.4 on the first derivative test and 4.6 on higher derivatives and concavity.
Integration Chapters—Chapter 5 begins with a section on antiderivatives—which could logically be included in the preceding chapter, but benefits from the use of integral notation. When the definite integral is introduced in Sections 5.3 and 5.4, we emphasize endpoint and midpoint sums rather than upper and lower and more general Riemann sums. This concrete emphasis carries through the chapter to its final section on numerical integration. Chapter 6 begins with a largely new section on Riemann sum approximations, with new examples centering on fluid flow and medical applications. Section 6.6 is a new treatment of centroids of plane regions and curves.
Chapter 8 (Techniques of Integration) is organized to accommodate those instructors who feel that methods of formal integration now require less emphasis, in view of modern techniques for both numerical and symbolic integration. Integration by parts (Section 8.3) precedes trigonometric integrals (Section 8.4). The method of partial fractions appears in Section 8.5, and trigonometric substitutions and integrals involving quadratic polynomials follow in Sections 8.6 and 8.7. Improper integrals appear in Section 8.8, with new and substantial subsections on special functions and probability and random sampling. This rearrangement of Chapter 8 makes it more convenient to stop wherever the instructor desires.
Calculus of Transcendental Functions—Section 7.1 (much strengthened for this edition) introduces the exponential and logarithmic functions from a fairly intuitive viewpoint; the approach based on the natural logarithm as an integral appears in Section 7.4. Sections 7.2 and 7.3 introduce 1'Hopital's rule and apply it to round out the calculus of exponential and logarithmic functions. Sections 7.5 and 7.6 cover both derivatives of and integrals involving inverse trigonometric functions and hyperbolic functions.
Differential Equations—This entirely new chapter begins with the most elementary differential equations and applications (Section 9.1) and then proceeds to introduce both graphical (slope field) and numerical (Eider) methods in Section 9.2. Subsequent sections of the chapter treat separable and linear firstorder differential equations and (in more depth than usual in a calculus course) applications such as population growth (including logistic and predatorprey populations) and motion with resistance. The final two sections of Chapter 9 treat secondorder linear equations and applications to mechanical vibrations. Instructors desiring still more coverage of differential equations can arrange with the publisher to bundle and use appropriate sections of Edwards and Penney, Differential Equations: Computing and Modeling 2/e (PrenticeHall, 2000).
Parametric Curves and Polar Coordinates—The principal change in Chapter 10 is the replacement of three separate sections in the 5th edition on parabolas, ellipses, and hyperbolas with a single Section 10.6 that provides a unified treatment of all the conic sections.
Infinite Series—After the usual introduction to convergence of infinite sequences and series in Sections 11.2 and 11.3, a combined treatment of Taylor polynomials and Taylor series appears in Section 11.4. This makes it possible for the instructor to experiment with a briefer treatment of infinite series, but still offer exposure to the Taylor series that are so important for applications. The principal change in Chapter 11 is the addition of a new final section on power series methods and their use to introduce new transcendental functions, thereby concluding the middle third of the book with a return to differential equations.
Multivariable Calculus—The treatment of calculus of more than a single variable is rather traditional, beginning with vectors, curves, and surfaces in Chapter 12. Chapter 13 features a strong treatment of multivariable maximumminimum problems in Sections 13.5 (initial approach to these problems), 13.9 (Lagrange multipliers), and 13.10 (critical points of functions of two variables). Chapters 13 (Partial Differentiation), 14 (Multiple Integrals), and 15 (Vector Calculus) have been significantly rewritten for this edition.
OPTIONS IN TEACHING CALCULUS
The Calculus Sequence—The present version of the text is accompanied by a less traditional version that treats transcendental functions earlier in singlevariable calculus and includes matrices for use in multivariable calculus. Both versions of the complete text are also available in twovolume split editions. By appropriate selection of first and second volumes, the instructor can therefore construct a complete text for a calculus sequence with
MaximumMinimum Problems—The text includes first coverage of maximumminimum problems in Chapter 3 (Sections 3.5 and 3.6) to provide early motivation in the form of concrete applications of the derivative, and then returns with the first and secondderivative tests of Sections 4.4 and 4.6. However, some instructors may prefer to treat these applications later—following trigonometric derivatives and related rates, and along with the bulk of the associated material in Chapter 4. The modular character of the pertinent sections in these two differential calculus chapters permits such desired rearrangements of the material within the typical pair of instructional units (each likely followed by its own hour test). For instance, Sections 3.5 and 3.6 on maxmin problems can be deferred and used to begin the second unit on differential calculus, after appending Sections 4.1 (Implicit Differentiation and Related Rates) and 4.2 (Increments, Differentials, and Linear Approximation) to the first unit. Thus the material in Chapters 3 and 4 would be covered in the following order.
Unit I: Differentiation
3.1 The Derivative and Rates of Change
3.2 Basic Differentiation Rules
3.3 The Chain Rule
3.4 Derivatives of Algebraic Functions
