The end-of-chapter review has been expanded to include Important Concepts. This new feature summarizes the key theorems, formulas, and equations from the chapter. Important Concepts together with Important Terms provides students with a comprehensive and useful tool for study and review.
-
Updated problem sets include many new exercises that use real data with modern business applications, further reinforcing the relevance of this material to applied math students.
-
The book's technology program has been expanded, offering more options to meet the expectations and needs of today's instructors and students. Enhanced WebAssign®, available with the text, includes an increased number of problems and supporting assets. In addition, the Rolf package now includes YouBook (an interactive eBook version of the text that instructors can customize), CourseMate, and a hybrid version of the text.
-
Discussions and keystroke instructions in Using Excel have been updated to Excel 2007 and Excel 2010.
-
Detailed computations enable students to easily follow successive steps in the problem-solving process.
-
More than 3,200 exercises and 500 examples offer instructors and students with an abundance of homework and practice problems. Examples and exercises are cross-referenced, identifying for students a corresponding exercise to check their understanding after they read through an example and solution.
-
Exercises are graded by level of difficulty: level 1 for routine problems, level 2 for elementary word problems, and level 3 for more thought-provoking problems.
-
Discussion questions provide the option of using the graphing calculator or spreadsheet technology to solve the problem. "Explorations" encourage students to think more deeply about mathematical concepts, often providing an opportunity to use the graphing calculator. Many of these exercises may be used for group projects or writing assignments.
-
References to technology keep the text current with new applications. "Using Your TI Graphing Calculator" and "Using Excel" boxes walk students through the steps necessary to apply the technology to selected exercises. Additional guidance on how to use the graphing calculator is found in an appendix.
