INDEX.

- The data in examples and exercises have been updated. New examples have been added (see Examples 6.1.5, 11.2.5, and 14.3.3, for instance), and the solutions to many of the existing examples have been enhanced.
- Several new applications-based problems have been added to help students strengthen their understanding of concepts and make the leap towards discovering the impact of Calculus in its various applications.
- Three new projects have been added: the project, Controlling Red Blood Cell Loss During Surgery describes the ANH procedure, in which blood is extracted from the patient before an operation and is replaced by saline solution. This dilutes the patient’s blood so that fewer red blood cells are lost during bleeding and the extracted blood is returned to the patient after surgery. The project, Planes and Birds: Minimizing Energy asks how birds can minimize power and energy by flapping their wings versus gliding. In the project, The Speedo LZR Racer Suit, it is explained that this suit reduces drag in the water and, as a result, many swimming records were broken. Students are asked why a small decrease in drag can have a big effect on performance.
- More than 20% of the exercises in each chapter are new. Here are some Author favorites: 2.7.61, 2.8.36-38, 3.1.79-80, 3.11.54, 4.1.69, 4.3.34, 4.3.66, 4.4.80, 4.7.39, 4.7.67, 5.1.19-20, 5.1.67-68, 5.4.70, 6.1.51, 7.4.67, 8.1.39, 12.5.81, 12.6.29-30, 14.6.65-66.

- Four carefully-crafted diagnostic tests in algebra, analytic geometry, functions, and trigonometry appear at the beginning of the text. These provide students with a convenient way to test their preexisting knowledge and brush up on skill techniques they need to successfully begin the course. Answers are included, and students who need to improve will be referred to points in the text or on the book's website where they can seek help.
- Stewart's presentation repeatedly provides answers to the question, “When will I use this?” You'll find many examples of how calculus is used as a problem-solving tool in fields such as physics, engineering, chemistry, biology, medicine, and the social sciences.
- Stewart's text offers an extensive collection of more than 8,000 quality exercises. Each exercise set is carefully graded, progressing from skill-development problems to more challenging problems involving applications and proofs. The wide variety of types of exercises includes many technology-oriented, thought-provoking, real, and engaging problems.
- A wealth of engaging projects reinforce concepts. "Writing Projects" ask students to compare present-day methods with those of the founders of calculus. "Discovery Projects" anticipate results to be discussed later. "Applied Projects" feature content that engages student interest and demonstrates the real-world use of mathematics. "Laboratory Projects" anticipate results to be discussed later or encourage discovery through pattern recognition.
- "Strategies" sections (based on George Polya's problem-solving methodology) help students select what techniques they'll need to solve problems in situations where the choice is not obvious, and help them develop true problem-solving skills and intuition.
- Historical and biographical margin notes enliven the course and show students that mathematics was developed to help explain and represent natural phenomena.
- More challenging exercises called "Problems Plus" follow the end-of-chapter exercises. These sections reinforce concepts by requiring students to apply techniques from more than one chapter of the text, and by patiently showing them how to approach a challenging problem.
