## 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**, **Precalculus** 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.
