• Jeffery Cole

Jeffery A. Cole has been teaching mathematics and computer science at Anoka-Ramsey Community College since fall 1981. He started working on the Swokowski series of precalculus texts in 1985 as an ancillary author, and has been a co-author since 1991. His contribution to the Swokowski texts also includes joining the revision team of the calculus text in 1989.

• A new Chapter 11-- Limits of Functions--provides students a solid foundation on limit concepts and prepares them for any beginning Calculus course.

• Appendix V--Theorems on Limits--contains proofs for some of the theorems in Chapter 11.

• New examples and exercises have been incorporated throughout, keeping the material current and fresh.

• Great care is taken to explain each concept and include step-by-step comments in the solutions of the examples. Many examples are accompanied by graphs, figures, charts or tables to help students interpret graphical data.

• Each exercise set is carefully graded, progressing from basic skill-building problems to more challenging conceptual and applied problems.

• The text includes a wealth of interesting and relevant applications designed to capture student interest and help students relate the material to real-life situations.

• Graphing calculator inserts, examples and exercises, highlight the capabilities of graphing calculators and illustrate how to use graphing calculators to solve problems more quickly.

• Suitable for small group discussions, Discussion Exercises contain a mix of theoretical and application-oriented exercises.
