## Overview

Larson's PRECALCULUS HYBRID, Ninth Edition, delivers the same sound, consistently structured explanations and exercises of mathematical concepts as his market-leading hardcover text, PRECALCULUS, Ninth Edition, combined with a briefer paperback format that engages students online with Enhanced WebAssign®. The HYBRID demonstrates Larson's commitment to revolutionizing the way instructors teach and students learn material by moving all the end-of-section exercises from the text online as well as incorporating more real-world applications, ongoing review, and innovative technology. Each new Larson HYBRID includes immediate student access to Enhanced WebAssign®. The ninth edition features "How Do You See It?" exercises that 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® offers 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.

- State-of-the-art package provides a cost-effective, briefer option for students--all end-of-section exercises are omitted from the text and appear online only and each new HYBRID includes immediate access to WebAssign® and the Cengage YouBook.
- Enriched remarks reinforce or expand on 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 homework support through CalcChat.com, an independent website, provides students with free solutions to all odd-numbered problems in the text.
- WebAssign® features fully integrated content from the text, including all end-of-section problems and chapter tests, as well as problem-specific videos, animations, and lecture videos. The robust online homework solution allows instructors to assign, collect, grade, and record homework assignments online, minimizing workload and streamlining the grading process. It also gives students the ability to stay organized with assignments and have up-to-date grade information.
- Fresh chapter openers highlight real-life problems that connect to the examples and exercises presented 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.

- "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's PRECALCULUS HYBRID is ideal for a two-term course.
