· Many of the exercises have been revised to ensure they are scaffolded in difficulty level from easy to challenging.
Technical Applications: The technical applications provide motivation for the student, and examples for an instructor who may not have a technical background. Additionally, an Index to Applications aids in finding applications in a particular field, such as electrical technology.
Estimation: Shows a student whether an answer is reasonable or not reasonable. They show common pitfalls for both student and instructor and are flagged and boxed, wherever appropriate.
Formulas used in the text are boxed and numbered, and listed in the Appendix as the Summary of Facts and Formulas.
Writing, Projects, Internet: Every chapter concludes with a section of optional enrichment activities. Many students are attracted to the magic and history of mathematics and welcome a guided introduction into this world. These writing questions aim to test and expand a student's knowledge of the material and perhaps explore areas outside of those covered in class while team projects foster "collaborative learning."
