For courses in Precalculus.

Michael Sullivan's time-tested approach helps students focus on the fundamental skills they need for the course: preparing for class, practicing with homework, and reviewing the concepts. The 11th Edition continues to evolve to meet the needs of today's students.

This series prepares and supports students with access to help, where and when they require it. The hallmark Sullivan cycle of continuous preparation and retention—along with the high-quality exercises that Sullivan texts are known for—gives students the reinforcement they need.
