## Description

**Mike Sullivan’s**time-tested approach focuses students on the fundamental skills they need for the course:

*preparing*for class,

*practicing*with homework, and

*reviewing*the concepts. In the

**Ninth Edition**,

**Trigonometry: A Unit Circle Approach**has evolved to meet today’s course needs, building on these hallmarks by integrating projects and other interactive learning tools for use in the classroom or online. New Internet-based Chapter Projects apply skills to real-world problems and are accompanied by assignable MathXL exercises to make it easier to incorporate these projects into the course. In addition, a variety of new exercise types, Showcase examples, and video tutorials for MathXL exercises give instructors even more flexibility, while helping students build their conceptual understanding.

**CourseSmart textbooks do not include any media or print supplements that come packaged with the bound book.**
