xxiv Preface to the Instructor The figures (created in GeoGebra, many by Michael Sullivan III) illustrate key concepts and allow manipulation. They have been designed to be used in lecture as well as by students independently. • NEW! ▲ GeoGebra Graphing Exercises—Gradable graphing exercises that help students demonstrate their understanding. They enable students to interact directly with the graph in a manner that reflects how students would graph on paper. • Enhanced Assignments—These section-level assignments have three unique properties (and are fully editable). (1) They help keep skills fresh with spaced practice of previously learned concepts. The spaced practice problems are selected from the Retain Your Knowledge problems in the textbook. (2) They have learning aids strategically turned off for some exercises to ensure that students understand how to work the exercises independently. (3) They contain personalized prerequisite skills exercises for gaps identified in the chapter-level Skills Check Quiz. Using the Ninth Edition Effectively with Your Syllabus To meet the varied needs of diverse syllabi, this text contains more content than is likely to be covered in a Precalculus course. As the chart illustrates, this text has been organized with flexibility of use in mind. Within a given chapter, certain sections are optional (see the details that follow the figure below) and can be omitted without loss of continuity. 2 1 Appendix 10.1210.4 10.5210.7 9.129.3 3 4 5 6 12 14 11 13 7 8 9.429.7 Appendix Review This chapter consists of review material. It may be used as the first part of the course or later as a just-in-time review when the content is required. Specific references to this chapter occur throughout the text to assist in the review process. Chapter 1 Graphs This chapter lays the foundation for functions. Chapter 2 Functions and Their Graphs Perhaps the most important chapter. Section 2.6 is optional. Chapter 3 Linear and Quadratic Functions Topic selection depends on your syllabus. Sections 3.2 and 3.4 may be omitted without loss of continuity. Chapter 4 Polynomial and Rational Functions Topic selection depends on your syllabus. Chapter 5 Exponential and Logarithmic Functions Sections 5.1–5.6 follow in sequence. Sections 5.7, 5.8, and 5.9 are optional. Chapter 6 Trigonometric Functions Section 6.6 may be omitted in a brief course. Chapter 7 Analytic Trigonometry Sections 7.2 and 7.7 may be omitted in a brief course. Chapter 8 Applications of Trigonometric Functions Sections 8.4 and 8.5 may be omitted in a brief course. Chapter 9 Polar Coordinates; Vectors Sections 9.1–9.3 and Sections 9.4–9.7 are independent and may be covered separately. Chapter 10 Analytic Geometry Sections 10.1–10.4 follow in sequence. Sections 10.5, 10.6, and 10.7 are independent of each other, but each requires Sections 10.1–10.4. Chapter 11 Systems of Equations and Inequalities Sections 11.2–11.7 may be covered in any order, but each requires Section 11.1. Section 11.8 requires Section 11.7. Chapter 12 Sequences; Induction; The Binomial Theorem There are three independent parts: Sections 12.1–12.4; Section 12.5; and Section 12.6. Chapter 13 Counting and Probability The sections follow in sequence. Chapter 14 A Preview of Calculus: The Limit, Derivative, and Integral of a Function If time permits, coverage of this chapter will give your students a beneficial head start in calculus.
