The Calculus by William V. Smith
Publisher: Brigham Young University 2001
Here is a free online calculus course. This is essentially an ordinary text, but you can read it online. There are lots of exercises and examples. This text is somewhat unusual for two reasons. The text is rigorous. (Proofs are done for nearly everything - eventually.) We do calculus in both one and two variables at the same time.
