Calculus Without Limits

John C. Sparks is a senior staff engineer at Wright-Patterson Air Force Base in Dayton, Ohio with approximately thirty-one years of engineering and management experience. In addition to his Air Force career, Sparks has taught mathematics at Sinclair Community College for over twenty years. In late 2003, Sparks received the Ohio Association of Two-Year Colleges’ 2002-2003 Adjunct Teacher of the Year award. He and his wife, Carolyn (photo), have celebrated thirty-five years of marriage and have two sons, Robert and Curtis, who are both married. Sparks is a lifelong resident of Xenia, Ohio. Sparks has written and published three volumes of poetry, Rhyme for All Seasons, Mixed Images, and Gold, Hay and Stubble: One Journeyman’s Poetic Diary. Calculus without Limits is his first full-length mathematics work; and, with its publication, a thirty-year old dream is realized.
