Need to Review? Model It! Prepare for Class: “Read the Book” Feature Description Benefit Page(s) Every Chapter begins with . . . Chapter-Opening Topic & Project Each chapter begins with a discussion of a topic of current interest and ends with a related project. In the concluding project, you will apply what you have learned to solve a problem related to the topic. 272, 381 Internet-Based Projects These projects allow for the integration of spreadsheet technology that you will need to be a productive member of the workforce. The projects give you an opportunity to collaborate and use mathematics to deal with issues of current interest. 381 Every Section begins with . . . LEARNING OBJECTIVES Each section begins with a list of objectives. Individual objectives also appear in the text where they are covered. These objectives focus your studying by emphasizing what’s most important and where to find it. 294 Sections contain . . . PREPARING FOR THIS SECTION Most sections begin with a list of key concepts to review, with page numbers. Ever forget what you’ve learned?This feature highlights previously learned material to be used in this section. Review it, and you’ll always be prepared to move forward. 294 Now Work the ‘Are You Prepared?’ Problems These problems assess whether you have the prerequisite knowledge for the upcoming section. Work the ‘AreYou Prepared?’ problems. If you get one wrong, you’ll know exactly what you need to review and where to review it! 294, 306 Now Work PROBLEMS These follow most examples and direct you to a related exercise. We learn best by doing.You’ll solidify your understanding of examples if you try a similar problem right away, to be sure you understand what you’ve just read. 302, 308 CAUTION Words of caution are provided in the text. These point out common mistakes and help you avoid them. 330 Explorations and Seeing the Concept These activities foreshadow a concept or reinforce a concept just presented. You will obtain a deeper and more intuitive understanding of theorems and definitions. 289, 301 In Words This feature provides alternative descriptions of select definitions and theorems. This feature translates math into plain English. 313 Calculus This symbol appears next to information essential for the study of calculus. Foreshadowing calculus now will make the material easier later. 68, 277, 302 These examples provide “how to” instruction by offering a guided, step-bystep approach to solving a problem. With each step presented on the left and the mathematics displayed on the right, you can immediately see how each step is employed. 206–207 Examples and Problems These examples and problems require you to build a mathematical model from either a verbal description or data. The homework Model It! problems are marked by purple problem numbers. It is rare for a problem to come in the form “ Solve the following equation.” Rather, the equation must be developed based on an explanation of the problem.These problems require you to develop models that will enable you to describe the problem mathematically and suggest a solution to the problem. 320, 352 These margin notes provide a just-intime reminder of a concept needed now, but covered in an earlier section of the book. Each note is back-referenced to the chapter, section and page where the concept was originally discussed. Sometimes as you read, you encounter a word or concept you know you’ve seen before, but don't remember exactly what it means.This feature will point you to where you first learned the word or concept. A quick review now will help you see the connection to what you are learning for the first time and make remembering easier the next time. 301 SHOWCASE EXAMPLES
