Calculus without Limits is an original exposition of single-variable calculus using the classic differential approach. Written in an engaging, popular style by an award-winning mathematics teacher, Calculus without Limits is the first completely new calculus book to hit the shelves in approximately 95 years that deliberately minimizes the use of limits, one of the major stumbling blocks initially standing in the way of calculus students: not since Silvanus P. Thompson released the First Edition of Calculus made Easy in 1910 has an original self-study exposition of 'calculus without limits' been made publicly available. Thoroughly modern in style, Calculus without Limits has been fully infused with the author's own rich heritage as a baby-boomer growing up in the Dayton, Ohio area-home of the Wright Brothers and Wright-Patterson Air Force Base, the major research and development center of the United States Air Force. Hence, much of the unique pedagogy found therein is drawn from his continuing 'aerospace' and 'space age' experience.
