Trigonometry Enhanced with Graphing Utilities (4th Edition)
Mike SullivanProfessor of Mathematics at Chicago State University received a Ph.D. in mathematics from Illinois Institute of Technology. Mike has taught at Chicago State for over 30 years. He is a native of Chicago’s South Side and currently resides in Oaklawn.  Mike has four children.  The two oldest have degrees in mathematics and assisted in proofing, checking examples and exercises, and writing solutions manuals for this project.  Mike III co-authored the SullivanGraphing with Data Analysisseries as well as this series.  Dan, the youngest, sells for Prentice Hall as a generalist. Mike has authored or co-authored over ten books.  He owns a travel agency, and splits his time between a condo in Naples, Florida and a home in Oaklawn, where Mike enjoys gardening.  Mike first signed this series with Deleen Publishing (Acquired by Macmillan) in 1985. Mike Sullivan IIIis a professor of mathematics at Joliet Junior College.  He holds graduate degrees from Depot University in both mathematics and economics.  Mike has co-authored both of the Sullivan graphing series and collaborated with his sister to author supplements for all of the Sullivan series. Mike has recently authored a brand new successful Statistics book for Prentice HallFundamentals of Statistics, 1/e 2005 and Statistics: Informed Decisions Using Data, 1/e, 2004. Mike is currently working on a developmental math series for Prentice Hall that will be published in 2007. Mike is the father of three children.  He is an avid golfer and tries to spend as much of his limited free time as possible on the golf course. Why We Wrote the Book: Work on this series began with a unique perspective.  Teaching at a large urban institution and a smaller two-year college has allowed us to see firsthand the challenges associated with teaching students with diverse backgrounds in an urban setting.  Successful textbooks must be accessible to students.  As lead author of this series, one of the most important things I bring to the project is my experience as author of a successful calculus text.  Mike and I are both aware that students must be prepared in a Precalculus course for subsequent mathematics courses.  We also realize that many College Algebra students will not be going on to take upper level math courses.  In this series we resolved the seeming dilemma without sacrificing accessibility. The books in this series are designed to be mathematically comprehensive and to provide substantial mathematical preparation for subsequent courses.  At the same time, great effort has been expended to motivate the material and to make it accessible to even poorly prepared students.
