## Overview

Larson's ALGEBRA AND TRIGONOMETRY is ideal for a two-term course and known for delivering sound, consistently structured explanations and carefully written exercises of the mathematical concepts. With the Ninth Edition, the author continues to revolutionize the way students learn material by incorporating more real-world applications, on-going 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. Enhanced WebAssign features fully-integrated content from the text, with the addition of End-of-Section problems and Chapter Tests, as well as problem-specific videos, animations and lecture videos.

- Fresh Chapter Openers highlight real-life problems that connect to the examples and exercises presenting in the following chapter.
- Innovative Summarize Features help students organize the lesson's key concepts into a concise summary, providing a valuable study tool at the end of each section.
- Unprecedented How Do You See It? Exercises in every section present real-life problems that students solve by visual inspection using the concepts in the lesson.
- Original Checkpoint Problems encourage immediate practice and check students' understanding of the concepts in the paired example.
- New Series Companion Website features chapter projects, data tables, assessments, study tools, video solutions and more to support students outside the text.
- Enhanced Exercise Sets deliver more rigor, relevancy and coverage than ever before and feature multi-step, real-life exercises to reinforce problem-solving skills and mastery of concepts
- Expanded Section Objectives offer students the opportunity to preview what will be presented in the upcoming section.
- Enriched Remarks reinforce or expand upon concepts helping students learn how to study mathematics, avoid common errors, address special cases, or show alternative or additional steps to a solution of an example.
- Up-to-the-minute student support through CalcChat.com, an independent website, provides students with free solutions to all odd-numbered problems in the text.

- Side-By-Side Examples help students not only see that a problem can be solved in more than one way but 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 ALGEBRA AND TRIGONOMETRY is ideal for a two-semester course.
