# Trigonometry, 9th Edition

### Overview

Larson's TRIGONOMETRY is known for delivering sound, consistently structured explanations and exercises of mathematical concepts. With the ninth edition, the author continues to revolutionize the way students learn material by incorporating more real-world applications, ongoing review, and innovative technology. How Do You See It? exercises give students practice applying the concepts, and new Summarize features, Checkpoint problems, and a Companion Website reinforce understanding of the skill sets to help students better prepare for tests.

### Features and Benefits

• Side-By-Side Examples help students see not only that a problem can be solved in more than one way but also how different methods--algebraically, graphically, and numerically--yield the same result. The side-by-side format also addresses many different learning styles.
• Algebra Helps direct students to sections of the textbook where they can review algebra skills needed to master the current topic.
• Technology Features offer suggestions for effectively using tools such as calculators, graphing calculators, and spreadsheet programs to deepen student understanding of concepts, ease lengthy calculations, and provide alternate solution methods for verifying answers obtained by hand.
• Historical Notes provide helpful information regarding basic mathematical foundations.
• Algebra of Calculus Examples and Exercises throughout the text emphasize various algebraic techniques used in calculus.
• Vocabulary Exercises at the beginning of the exercise set for each section help students review previously learned vocabulary terms necessary to solve the section exercises.
• Student Projects in various sections and online feature in-depth applied exercises with large, real-life data sets, where students create or analyze models.
• Chapter Summaries include explanations and examples of the objectives taught in the chapter.
• Larson TRIGONOMETRY is ideal for a one-semester course.
