Preparing for Class

• All sections begin with just-in-time review to prepare students for the topics ahead.

• Preparing for This Section lists previously learned concepts that will be useful in the section ahead. Page references are included for easy review.
• Now Work "Are You Prepared?" problems support the Preparing for This Section feature, allowing students to check that they are ready to proceed to the section ahead or if they need to turn back for further review. These problems appear at the start of each exercise set.

• Within each section, students get guidance along the way to help them master the material and develop their problem-solving skills.

• "Now Work" Problems follow most examples, and direct students to a related exercise for immediate reinforcement of the skill or concept.
• Step-by-Step, Annotated Examples contain detailed intermediate steps with additional annotations to help students see specific nuances.
• Calculus icons appear next to information essential for the study of calculus. When the icon appears next to a definition, the notation used is consistent with that used in calculus.
• In Words provide alternative descriptions of select definitions and theorems, translating math into plain English.
• Cautions boxes point out common mistakes and help students avoid them.

Practicing Skills

• NEW! Retain Your Knowledge problems in the exercise set are based on the article "To Retain New Learning, Do the Math" published in the Edurati Review in which author Kevin Washburn suggests that "the more students are required to recall new content or skills, the better their memory will be.” It is frustrating when students cannot recall skills learned earlier in the course. To alleviate this recall problem, we have created "Retain Your Knowledge problems. These new exercises are assignable in MyMathLab.

• Assess Your Understanding appears at the end of every section and contains a variety of problems for students to master the skills they need.

• "Are You Prepared?" Problems appear at the start of every exercise set and help students determine exactly what they need to review and where to review it. This feature is referenced from the Preparing for This Section feature. Answers appear at the end of the section.
• Concepts and Vocabulary questions are fill-in the-blank and true/false items that assess students’ understanding of key definitions and concepts. These have been written to serve as reading quizzes and are now assignable in MyMathLab® and MathXL®.
• Skill Development problems provide straightforward practice, are organized by difficulty, and are correlated to section examples.
• Graphical problems use graphs in a variety of ways, supplementing students’ analytical understanding with graphical understanding.
• Now Work problems–many examples refer to a related problem in the exercise set, which are marked by a yellow pencil icon. If students get stuck while doing their homework, they can look for the closest Now Work problem and refer back to the related example.
• Mixed Practice problems offer comprehensive assessment of the skills learned in the section by asking questions that relate to more than one concept or objective. These problems may also require students to utilize skills learned in previous sections, helping them to see how concepts are tied together.
• Applications and Extensions allow students to apply their skills to real-world problems and to extend concepts learned in the section.
• DWR–Discussion, Writing, and Research problems– are marked by a special icon and red numbers. They support class discussion, verbalization of mathematical ideas, and writing and research projects.

Reviewing for Exams and Quizzes

• NEW! Guided Lecture Notes give students a note-taking guide that assist in taking thorough, organized, and understandable notes as they watch the Author in Action videos. The Notes ask students to complete definitions, procedures, and examples based on the content of the videos and book. By directing students into essential material, students can focus and retain the most important concepts. These notes help increase the success of your students in any course structure.
• Chapter Reviews at the end of each chapter offer a variety of convenient tools for students’ reference and review.

• "You Should be Able To…” is a list of every objective by section, with corresponding practice exercises. Doing the recommended exercises allows students to master the key concepts. If they get something wrong, they can easily review the examples and exposition and try again.
• Review Exercises provide comprehensive review and practice of key skills, matched to the Learning Objectives for each section. These problems combine exercises from all sections, giving students comprehensive review in one place.
• Practice Tests–the Review Exercises contain blue-numbered problems, which can be combined to constitute a Practice Test for the chapter.
• Chapter Tests contain about 15—20 problems that can help students prepare for in-class exams. For additional help, students can watch an instructor work out full solutions on the Chapter Test Prep Video on YouTube^™, or in MyMathLab.
• Cumulative Review problem sets appear at the end of every chapter after Chapter 1. They combine problems from previous chapters, providing an ongoing cumulative review.
