Assessments that reinforce key concepts

In-chapter Examples generally follow a three-part format of Strategy, Solution, and Significance to emphasize how to approach a problem, how to work with the equations, and how to check and generalize the result. Examples are often followed by Check Your Understanding questions and answers to help reinforce for students the important ideas of the examples. Problem-Solving Strategies in each chapter break down methods of approaching various types of problems into steps students can follow for guidance. The book also includes exercises at the end of each chapter so students can practice what they’ve learned.

  • Conceptual questions do not require calculation but test student learning of the key concepts.
  • Problems categorized by section test student problem-solving skills and the ability to apply ideas to practical situations.
  • Additional Problems apply knowledge across the chapter, forcing students to identify what concepts and equations are appropriate for solving given problems. Randomly located throughout the problems are Unreasonable Results exercises that ask students to evaluate the answer to a problem and explain why it is not reasonable and what assumptions made might not be correct.
  • Challenge Problems extend text ideas to interesting but difficult situations.

Answers for selected exercises are available in an Answer Key at the end of the book.
