Trigonometry (Coburn), 2nd EditionAbout the AuthorsJohn Coburn grew up in the Hawaiian Islands, the seventh of sixteen children. In 1979he received a bachelor’s degree in education from the University of Hawaii. After being
lured into the business world for a number of years, he returned to his first love, accepting
a teaching position in high school mathematics where he was recognized as Teacher
of the Year in 1987. Soon afterward, John decided to seek a master’s degree, which he
received two years later from the University of Oklahoma. For the last fifteen years, he
has been teaching mathematics at the Florissant Valley campus of St. Louis Community
College, where he is now a full professor. During his tenure there he has received numerous
nominations as an outstanding teacher by the local chapter of Phi Theta Kappa, and
was recognized as Post–Secondary Teacher of the Year in 2004 by the Mathematics Educators
of Greater St. Louis (MEGSL). He has made numerous presentations at local,
state, and national conferences on a wide variety of topics. His other loves include his
family, music, athletics, games, and all things beautiful. We hope this love of life comes
through in his writing, and serves to make the learning experience an interesting and
engaging one for all students.
J.D. Herdlick was born and raised in St. Louis, Missouri, very near the Mississippi river. In 1992, he received his bachelor’s degree in mathematics from Santa Clara University (Santa Clara, California). After completing his master’s in mathematics at Washington University (St. Louis, Missouri) in 1994, he felt called to serve as both a campus minister and an aid worker for a number of years in the United States and Honduras. He later returned to education and spent one year teaching high school mathematics, followed by an appointment at Washington University as visiting lecturer, a position he held until 2006. Simultaneously teaching as an adjunct professor at the Meramec campus of St. Louis Community College, he eventually joined the department full time in 2001. While at Santa Clara University, he became a member of the honorary societies Phi Beta Kappa, Pi Mu Epsilon, and Sigma Xi under the tutelage of David Logothetti, Gerald Alexanderson, and Paul Halmos. In addition to the Dean’s Award for Teach-ing Excellence at Washington University, J.D. has received numerous awards and accolades for his teaching at St. Louis Community College. Outside of the office and classroom, he is likely to be found in the water, on the water, and sometimes above the water, as a passionate wakeboarder and kiteboarder. It is here, in the water and wind, that he finds his inspiration for writing. J.D. and his family currently split their time between the United States and Argentina. |  |
