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