My logo goes here (eventually), but in the meantime, this seems appropriate:

The following are useful things for calculus. You will need to right click on the links and either Save Link As ... or (for MSIE) Save Target As ...

Sage for Newbies This is a reasonably understandable Sage guide, also incomplete and by a different person. You might find it helpful also. It tends to be more complete.
The Calculus 1 book (PDF format) Completely revised for the new three-semester sequence in Calculus. There is a brand new chapter, and a lot more commentary. Size: 2723005 bytes.
Zipped version of Calculus 1 book This is the identical Calculus 1 text, but zipped. It is slightly smaller, so it might download a small amount faster. Note that the Asbury firewall sometimes gets twitchy downloading zip files. Size: 2540574 bytes.
The Calculus 2 book (PDF format This will be the newly-revised Calculus 2 book. At least when I get it done. Size: ???? bytes.
Zipped version of Calculus 2 book This will be the identical calculus II text, but zipped for slightly faster downloads, but again, the Asbury firewall can get grumpy about downloading zip files. Size: ???? bytes.
How To Use Sage book This is a work-in-progress, but it contains plenty of usable information now. It will be updated as I get time to work on it. It is useful for more advanced courses as well.

The following item is for more advanced mathematics, specifically for Dr. Coulliette's upper-level courses. Download instructions are the same.

My LaTeX guide: A Running Introduction to LaTeX; useful for getting started with LaTeX, which every mathematician needs to know.
