Objectives
Actionable objectives at the beginning of each section help to focus attention on key concepts. These objectives are reflected in the headings throughout that section and are revisited in a table at the end of the chapter, where they are linked to examples and specific Review Exercises.

Blue Equations Notes
**Blue Equations Notes **provide additional support by** **explaining calculations or indicating specific rules that are used in worked equations.

Case Study and Chapter Project
Each chapter opens with a case study that demonstrates how major concepts in the chapter apply to contemporary situations. The chapter project at the end of the chapter asks students to solve questions related to the case study.

Need to Review? and Recall
Need to Review? margin notes provide page references where students can review concepts that form the foundation for the current discussion. Recall notes offer students a quick refresher of key results that might help their understanding of theorems, definitions, formulas, and concepts.

Notes and Cautions
**Notes and Cautions **provide supporting details or warnings about common pitfalls.

In Words
In Words notes translate complex formulas, theorems, proofs, rules, and definitions into plain language.

Origins
**Origins** give biographical information or historical details about key figures and discoveries in the development of calculus.

Now Work
Now Work callouts, which follow most examples, give students an opportunity to reinforce the development of new skills by directing them to related section exercises.

Definitions and Theorems
Definitions and Theorems are highlighted in the text and are written in simple, clear, consistent language.

Section Exercise Sets
**Section Exercise Sets** develop studentsâ€™ skills and conceptual understanding. These exercises are divided into four categories and vary in levels of difficulty from routine, to moderate, to more challenging and are paired for easy assignments.

Chapter Review
**Chapter Reviews** summarize the key theorems, definitions, and formulas presented in the chapter.

End-of-Chapter Review Exercises
** End-of-Chapter Review Exercises **offer a comprehensive set of exercises that reinforce the chapterâ€™s key concepts and correspond to the section learning objectives.
