Precalculus: Pearson New International Edition (Electronic book text, 9th)

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. 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."
