This one-year calculus textbook is written for use with the author's calculus software package, MicroCalc release 7.0 (and earlier), a numerical computing and graphing software package developed explicitly for calculus instruction. For colleges teaching calculus using computers, this is an inexpensive, accurate, and easy-to-use program. The text covers standard single-variable topics, comparable to any text in the subject. It is directly keyed to the software and has taken advantage of the computer based nature of the course. MicroCalc is fully menu-driven, with excellent functionality and low maintenance.
