NEW DISCOVERY PROJECTS GUIDE STUDENTS IN APPLYING THE CONCEPTS THEY'VE MASTERED: Several new Discovery Projects in this edition feature applications or extensions of the concepts that students have just studied in the text. Discover/Discuss/Prove/Write problems at the end of every section encourage students to develop and strengthen their conceptual, critical-thinking and writing skills.

NEW CHAPTER UNITES KEY TOPICS: The new Chapter 8, "Polar Coordinates, Parametric Equations, and Vectors," unites the topics under the theme of describing curves and motion in a coordinate plane. The applications in the chapter demonstrate the need for different coordinate systems. In the "Focus on Modeling" following the chapter, both parametric equations and vectors are used to model the path and velocity of a projectile.

NEW REVIEW MATERIAL REINFORCES STUDENT UNDERSTANDING: Updated, effective review material at the end of most chapters now includes a matching exercise to reinforce the fundamental relationship between graphs and equations. This important review also includes a summary of properties and formulas. In addition, a Concept Check provides a step-by-step review of all of the main concepts and applications from the chapter.

NEW EXERCISES HELP STUDENTS DEVELOP IMPORTANT PROBLEMSOLVING SKILLS: New Problem-Solving exercises in most sections highlight and apply a specific problem-solving principle from the prologue. More than 20% of the overall exercises are new to this edition.

NEW EXPANDED PROBLEMS IN WEBASSIGN INCLUDE MULTIPLE PARTS TO ENSURE UNDERSTANDING: This edition's new online Expanded Problems take understanding well beyond the basic exercises. These problems ask students to show the specific steps of their work or to explain the reasoning behind the answers they've provided.

NEW REMEDIAL SUPPORT PREPARES STUDENTS FOR SUCCESS: Revisions throughout Chapter 1 review fundamentals while WebAssign digital resources provide prerequisite support to address readiness gaps, including the College Math Readiness Bootcamp and Just-in-Time review exercises. This edition also offers an expanded Geometry Review appendix that now highlights main concepts from geometry used in this edition, including congruence, similarity, the Pythagorean Theorem, parallel lines and circles.
