Precalculus courses are designed as the fourth course in a five-year sequence of college preparatory mathematics for high school students.

Precalculus 3rd Edition is designed similarly to the Core Connections courses and meets all of the standards for a Common Core fourth year high school math course, and includes an introduction to calculus with functions, graphs, limits, area under a curve, and rates of change. Careful consideration was given to the sequencing of the concepts in the course to allow for mastery over time while meeting the content standards of a fourth year course. The book is designed to allow teachers to choose topics that fit the needs of their students. The book can be used as a general fourth year math course or it can be used as a preparation for calculus course, depending on the topics that are chosen. Please note that the Precalculus 3rd Edition is not compatible with the current 2nd Edition for use side-by-side in a classroom.
