Product Details## Features & Benefits

{{collapseContainerClosed['features'] ? 'Show More' : 'Show Less'}}- 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.
- 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—algebraic, graphical, and numerical—yield the same result. The side-by-side format also addresses many different learning styles.
- Larson PRECALCULUS is ideal for one- or two-semester courses.
- ENHANCED WEBASSIGN: PRECALCULUS, Tenth Edition, is fully supported by Enhanced WebAssign (EWA), the powerful online homework and course management system that engages students in learning the math. EWA includes new end-of-chapter exercises, animated simulations, and pre-built assignments vetted by trusted subject matter experts along with robust course, section, assignment, and question settings and online testing to help instructors foster a deeper understanding of course concepts.
- The Student Companion Website features chapter projects, data tables, assessments, study tools, video solutions, and more to support students outside the text.
- CalcChat.com, an independent website, provides students with free, up-to-the-minute homework support, including solutions to all odd-numbered problems in the text.
- Algebra Helps features 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.
- Algebra of Calculus Examples and Exercises throughout the text emphasize various algebraic techniques used in calculus.
- Original Checkpoint Problems encourage immediate practice and check students' understanding of the concepts in the paired example.
