AM Page xii xii PREFACE Calculus, Seventh Edition, Hybrid Version, is similar to Calculus, Seventh Edition, in content and coverage except that all exercises are available only in Enhanced Web Assign. Essential Calculus is a much briefer book (800 pages), though it contains almost all of the topics in Calculus, Seventh Edition.

The relative brevity is achieved through briefer exposition of some topics and putting some features on the website.

The data in examples and exercises have been updated to be more timely.

Three new projects have been added: The Gini Index (page 429) explores how to measure income distribution among inhabitants of a given country and is a nice application of areas between curves.

The coverage of topics is not encyclopedic and the material on transcendental functions and on parametric equations is woven throughout the book instead of being treated in separate chapters.

Calculus: Early Vectors introduces vectors and vector functions in the first semester and integrates them throughout the book.
