Enhanced WebAssign! Easy to Use. Easy to Assign. Easy to Manage. Enhanced WebAssign is a user friendly way to assign, collect, grade, and record homework. Exercises come directly from the text and can be parameterized to ensure that every student has a parallel, but slightly different homework assignment. This complete learning system for students includes text-specific exercises, as well as tutorials, videos, and links to online tutoring, and eBook sections of the text. "Getting Ready for the Next Section" exercises are found in every problem set. This grouping of exercises ensures students have the requisite skills to perform the concepts discussed in the next section. Found throughout the text, "Using Technology" shows how calculators can be used to enhance learning and help solve problems. These boxes are easily identified and can be highlighted or skipped depending on instructor preference. Chapter openers motivate students to learn the topics in each chapter. Each chapter opener illustrates a real-world application of one of the main chapter topics, and most present the information both graphically and numerically. Hundreds of new problems and examples throughout the text include more contemporary applications. Additionally, wherever real data is used, it has been updated to reflect current statistics.
