New in the Book Chapter Opener applications with Infographics use current data and applications to present the math in context. These applications are linked to exercises in the text and MyMathLab course, as well as to other resources such as Active Learning Figures and Student Activities, to help students model, visualize, and learn the math. Reading Checks are designed for after reading the section, but before beginning the homework. Successful completion of a Reading Check indicates that the student is sufficiently prepared to work the section exercises. These are now also assignable in MyMathLab. Student Activities begin with real-world data and guide students to examine a key concept in each chapter, while analyzing the data and connecting other concepts. There is one activity per chapter and they are available in MyMathLab. Also available with MyMathLab MyMathLab is an online homework, tutorial, and assessment program designed to work with this text to engage students and improve results. Within its structured environment, students practice what they learn, test their understanding, and pursue a personalized study plan that helps them absorb course material and understand difficult concepts. The text and MyMathLab course form a tightly integrated program with all new To-the-Point Objective Videos, Active Learning Figures, and MyMathGuide workbook. Active Learning Figures are interactive animations that allow students to examine visual representations of concepts through both guided and open-ended exploration. These are linked to chapter openers andvother locations throughout the text and MyMathLab. Accompanying exercises provide additional practice and reinforcement.
