Three Distinct Series

Students have different goals, learning styles, and levels of preparation. Instructors have different teaching philosophics, styles, and techniques. Rather than write one series to fit all, the Sullivans have written three distinct series. All share the same goal to develop a high level of mathematical understanding and an appreciation for the way mathematics can describe the world around us. The manner of reaching that goal, however, differs from series to series.

Contemporary Series, Seventh Edition

The Contemporary Series is the most traditional in approach, yet modern in its treatment of precalculus mathematics. Graphing utility coverage is optional and can

be included or excluded based on instructor preference. College Algebra. College Algebra Essentials, Algebra & Trigonometry, Trigonometry. Precalculus. Precalculus Essentials

Enhanced with Graphing Utilities Series, Fourth Edition

This series provides a more thorough integration of graphing utilities into topies, al-lowing students to explore mathematical concepts and foreshadow ideas usually studied in later courses Using technology, the approach to solving certain problems differs from the Contemporary series, while the emphasis on understanding con-cepts and building strong skills does not.

College Algebra, College Algebra Essentials, Algebra & Trigonometry, Trigonometry, Precalculus

Graphing, Data, and Analysis Series, Third Edition

This series differs from the others, utilizing a functions approach which serves as the organizing principle tying concepts together. Each chapter introduces a new type of function, then develops all concepts pertaining to that particular function. The solu-tions of equations and inequalities, instead of being developed as stand-alone topics, are developed in the context of the underlying functions. Technology is integrated at the same level as the Enhanced with Graphing Utilities series (described above).
