This text was initially written by David Guichard. The single variable material in chapters 1–9 is a modification and expansion of notes written by Neal Koblitz at the University of Washington, who generously gave permission to use, modify, and distribute his work. New material has been added, and old material has been modified, so some portions now bear little resemblance to the original.

The book includes some exercises and examples from *Elementary
Calculus: An Approach Using Infinitesimals*, by H. Jerome Keisler,
available at
http://www.math.wisc.edu/~keisler/calc.html
under a Creative Commons license. In addition, the chapter on
differential equations is largely derived from the corresponding chapter in
Keisler's book.
Albert Schueller, Barry Balof, and Mike Wills have contributed
additional material.
