Preface
The ninth edition of Calculus for Business, Economics, Life Sciences, and Social Sciences is designed for a oneterm course in calculus and for students who have had 1  2 years of high school algebra or the equivalent. The choice and independence of topics make the text readily adaptable to a variety of courses (see the Chapter Dependency Chart on page xi). It is one of five books in the authors' college mathematics series.
Improvements in this edition evolved out of the generous response from a large number of users of the last and previous editions as well as survey results from instructors, mathematics departments, course outlines, and college catalogs. Fundamental to a book's growth and effectiveness is classroom use and feedback. Now in its ninth edition, Calculus for Business, Economics, Life Sciences, and Social Sciences has had the benefit of having a substantial amount of both.
Emphasis and Style
The text is written for student comprehension. Great care has been taken to write a book that is mathematically correct and accessible to students. Emphasis is on computational skills, ideas, and problem solving rather than mathematical theory. Most derivations and proofs are omitted except where their inclusion adds significant insight into a particular concept. General concepts and results are usually presented only after particular cases have been discussed.
Examples and Matched Problems
Over 290 completely worked examples are used to introduce concepts and to demonstrate problemsolving techniques. Many examples have multiple parts, significantly increasing the total number of worked examples. Eachexample is followed by a similar matched problem for the student to work while reading the material. This actively involves the student in the learning process. The answers to these matched problems are included at the end of each section for easy reference.
Exploration and Discussion
Every section contains Explore  Discuss problems interspersed at appropriate places to encourage the student to think about a relationship or process before a result is stated, or to investigate additional consequences of a development in the text. Verbalization of mathematical concepts, results, and processes is encouraged in these Explore  Discuss problems, as well as in some matched problems, and in some problems in almost every exercise set. The Explore  Discuss material also can be used as inclass or outofclass group activities. In addition, at the end of every chapter, we have included two special chapter group activities that involve several of the concepts discussed in the chapter. Problems in the exercise sets that require verbalization are indicated by color problem numbers.
Exercise Sets
The book contains over 4,100 problems. Many problems have multiple parts, significantly increasing the total number of problems. Each exercise set is designed so that an average or belowaverage student will experience success and a very capable student will be challenged. Exercise sets are mostly divided into A (routine, easy mechanics), B (more difficult mechanics), and C (difficult mechanics and some theory) levels.
Applications
A major objective of this book is to give the student substantial experience in modeling and solving realworld problems. Enough applications are included to convince even the most skeptical student that mathematics is really useful (see the Applications Index inside the back cover). Worked examples involving applications are identified by or . Almost every exercise set contains application problems, usually divided into business and economics, life science, and social science groupings. An instructor with students from all three disciplines can let them choose applications from their own field of interest; if most students are from one of the three areas, then special emphasis can be placed there. Most of the applications are simplified versions of actual realworld problems taken from professional journals and books. No specialized experience is required to solve any of the applications.
Internet Connections
The Internet provides a wealth of material that can be related to this book, from sources for the data in application problems to interactive exercises that provide additional insight into the various mathematical processes. Every section of the book contains Internet connections identified by . Links to the related web sites can be found at the PH Companion Website discussed later in this preface
Technology
The generic term graphing utility is used to refer to any of the various graphing calculators or computer software packages that might be available to a student using this book. (See the description of the software accompanying this book later in this Preface.) Although access to a graphing utility is not assumed, it is likely that many students will want to make use of one of these devices. To assist these students, optional graphing utility activities are included in appropriate places in the book. These include brief discussions in the text, examples or portions of examples solved on a graphing utility, problems for the student to solve, and a group activity that involves the use of technology at the end of each chapter. Beginning with the group activity at the end of Chapter 1, and continuing throughout the text, linear regression on a graphing utility is used at appropriate points to illustrate mathematical modeling with real data. All the optional graphing utility material is clearly identified by either or and can be omitted without loss of continuity, if desired.
Graphs
All graphs are computergenerated to ensure mathematical accuracy. Graphing utility screens displayed in the text are actual output from a graphing calculator.
Additional Pedagogical Features
Annotation of examples and developments, in small color type, is found throughout the text to help students through critical stages (see Sections 11 and 32). Think boxes (dashed boxes) are used to enclose steps that are usually performed mentally (see Sections 11 and 34). Boxes are used to highlight important definitions, results, and stepbystep processes (see Sections 11 and 32). Caution statements appear throughout the text where student errors often occur (see Sections 32 and 41). Functional use of color improves the clarity of many illustrations, graphs, and developments, and guides students through certain critical steps (see Sections 11 and 32). Boldface type is used to introduce new terms and highlight important comments. Chapter review sections include a review of all important terms and symbols and a comprehensive review exercise. Answers to most review exercises, keyed to appropriate sections, are included in the back of the book. Answers to all other oddnumbered problems are also in the back of the book.
Content
The text begins with the development of a library of elementary functions in Chapters 1 and 2, including their properties and uses. We encourage students to investigate mathematical ideas and processes graphically and numerically, as well as algebraically. This development lays a firm foundation for studying mathematics both in this book and in future endeavors. Depending on the syllabus for the course and the background of the students, some or all of this material can be covered at the beginning of a course, or selected portions can be referred to as needed later in the course.
The material in Part Two (Calculus) consists of differential calculus (Chapters 3  5), integral calculus (Chapters 6  7), multivariable calculus (Chapter 8), and a brief discussion of differentiation and integration of trigonometric functions (Chapter 9). In general, Chapters 3  6 must be covered in sequence; however, certain sections can be omitted or given brief treatments, as pointed out in the discussion that follows (see the Chapter Dependency Chart on page xi).
Chapter 3 introduces the derivative, covers the limit properties essential to understanding the definition of the derivative, develops the rules of differentiation (including the chain rule for power forms), and introduces applications of derivatives in business and economics. The interplay between graphical, numerical, and algebraic concepts is emphasized here and throughout the text.
Chapter 4 focuses on graphing and optimization. The first three sections cover continuity and firstderivative and secondderivative graph properties, while emphasizing polynomial graphing. Rational function graphing is covered in Section 44. In a course that does not include graphing rational functions, this section can be omitted or given a brief treatment. Optimization is covered in Section 45, including examples and problems involving endpoint solutions.
The first three sections of Chapter 5 extend the derivative concepts discussed in Chapters 3 and 4 to exponential and logarithmic functions (including the general form of the chain rule). This material is required for all the remaining chapters. Implicit differentiation is introduced in Section 54 and applied to related rate problems in Section 55. These topics are not referred to elsewhere in the text and can be omitted.
Chapter 6 introduces integration. The first two sections cover antidifferentiation techniques essential to the remainder of the text. Section 63 discusses some applications involving differential equations that can be omitted. Sections 64 and 65 discuss the definite integral in terms of Riemann sums, including approximations with various types of sums and some simple error estimation. As before, the interplay between the graphical, numeric, and algebraic properties is emphasized. These two sections also are required for the remaining chapters in the text.
Chapter 7 covers additional integration topics and is organized to provide maximum flexibility for the instructor. The first section extends the area concepts introduced in Chapter 6 to the area between two curves and related applications. Section 72 covers three more applications of integration, and Sections 73 and 74 deal with additional techniques of integration. Any or all of the topics in Chapter 7 can be omitted.
The first five sections of Chapter 8 deal with differential multivariable calculus and can be covered any time after Section 53 has been completed. Section 86 requires the integration concepts discussed in Chapter 6.
Chapter 9 provides brief coverage of trigonometric functions that can be incorporated into the course, if desired. Section 91 provides a review of basic trigonometric concepts. Section 92 can be covered any time after Section 53 has been completed. Section 93 requires the material in Chapter 6.
Appendix A contains a selftest and a concise review of basic algebra that also may be covered as part of the course or referred to as needed. As mentioned above, Appendix B contains additional topics that can be covered in conjunction with certain sections in the text, if desired.
Supplements for the Student
1. A Student Solutions Manual and Visual Calculus by Garret J. Etgen and David Schneider is available through your book store. The manual includes detailed solutions to all oddnumbered problems and all review exercises. Visual Calculus by David Schneider contains over twenty routines that provide additional insight into the topics discussed in the text. Although this software has much of the computing power of standard calculus software packages, it is primarily a teaching tool that focuses on understanding mathematical concepts, rather than on computing. These routines incorporate graphics whenever possible to illustrate topics such as secant lines; tangent lines; velocity; optimization; the relationship between the graphs of f, , ; and the various approaches to approximating definite integrals. All the routines in this software package are menudriven and very easy to use. The software will run on DOS or Windows platforms.
