Sullivan, Precalculus, 12th Edition
Michael Sullivan’s timetested approach focuses students on the fundamental skills they need for the AP® precalculus course: preparing for class, practicing with homework, and reviewing the concepts. The 12th Edition, published by Pearson, continues to evolve to meet the needs of today’s students:
 New and revised graphing utility screen captures include more Desmos and TI84 Plus images–they provide alternate ways of visualizing concepts and making connections between equations, data, and graphs in full color.
 Desmos simplifies finding points of interest such as local extrema, intercepts, and points of intersection with systems of equations.
 Need To Review? questions are a timely reference to the chapter, section and page where a student may need to refresh a particular skill needed for the material.
 Career Tips and Fun Facts help students connect the topic at hand to the world around them. Caution notes help students avoid common mistakes.
AP Precalculus Program for Middle and High Schoolers with Digital Integration
Precalculus features Sullivan’s proven cycle of continuous preparation and retention: prepare for class, practice with homework, and review concepts.
Revitalized with New Content
The 12th Edition adds many new and revised exercises and examples; adds new learning tips in margin notes; and updates all graphing utility content and images.
Features Integrated Review
Integrated Review is now included in all Sullivan 12th Edition MyMathLab® for School courses, including Precalculus.Integrated review can be used to help students who enter without a full understanding of prerequisite skills and concepts.

About the Author: Michael Sullivan
After graduating from Saint Ignatius College Prep (Chicago), Michael Sullivan attended DePaul University as an undergraduate, completing a major in mathematics and a minor in physics in 3 years. He pursued his graduate studies at the Illinois Institute of Technology, receiving a master's degree in 1963 and a Doctor of Philosophy (PhD) in 1967, both in mathematics.
Mike had a teaching career of over 30 years at Chicago State University as a Professor of Mathematics, where he honed an approach to teaching and writing that forms the foundation for his textbooks. He has authored more than 120 textbooks in mathematics and currently has 15 books in print. His textbooks are used in high schools and universities across the United States and have been translated into a variety of foreign languages. His books have been awarded both the Texty and McGuffey awards from the Textbook and Academic Authors Association (TAA), and in 2007 he received the TAA Lifetime Achievement Award. In 2023, Mike was awarded the Saint Ignatius College Prep Alumni Award for Excellence, in recognition of his outstanding commitment to his profession and to the Saint Ignatius community.
Mike is a member of the American Mathematical Association of TwoYear Colleges, the American Mathematical Society, the Mathematical Association of America, and the Textbook and Academic Authors Association. He has 4 children, all of whom are involved with mathematics or publishing. His son, Michael Sullivan III, also teaches college mathematics and is his coauthor on 2 Pearson precalculus series. He divides his time between living in Naples, FL and Oak Lawn, IL. When not writing textbooks he enjoys tennis, travel and gardening.
