Trigonometry

This revision of a bestseller is intended for a one-semester trigonometry course using a right-triangle approach. TRIGONOMETRY, 3/e emphasizes the understanding of definiitons, general principles, and their applications to problem solving. Features: * Identities are introduced early in Chapter 1, reviewed often, and covered in more detail in Chapter 5. * Exact values of the trigonometric functions are emphasized throughout the book. * Chapter Introductions explain what students can expect to find and list the previous material used to develop the concepts in the chapter. * Review problems are in every exercise set after Chapter 1, continually reinforcing what students have already learned as they build theor problem-solving skills. Whenever possible, these problems review material needed in the next section. * Problem sets follow a consistent format. The numerous drill exercises ensure proficiency, get progressively more difficult,and have odd-even similarities so students can check their work on an odd-numbered problem (answers are provided in the back of the text) and try a similar even problem. Also included are application problems and review problems.
* Chapter Summaries list all the properties and definitions found in the chapter, along with an example of the kind of problem associated with the topic. Chapter Tests allow students to assess their mastery of the chapter material. New to this edition: * New section openers feature an application problem of historical information that motivates students to appreciate the importance of mathematics: references to these introductory topics are carried through to topics later in the book. * New sections focus on finding the equation of a graph from the graph itself (Section 4.4) and understanding vectors written in the form v=ai + bj (Section 7.5). This encourages students to connect the algebraic and geometric interpretation of vectors. * Research Projects, scattered throughout, involve students in researching and writing on topics such as English, history, religion, and map making, encompassing the NCTM goals of increased writing and group activities.
