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. As we get the chapters scanned in, they will become highlighted so that you can click on them to read.
This text is somewhat unusual for two reasons.
Both points are no doubt controversial, but conceptually the approach gives a kind of clean synergy which generates important examples and unifies calculus to a great extent.
Unfortunately, there are no doubt uncorrected typographical errors and logical errors. Any corrections are appreciated. Send comments and/or corrections to me. I will make corrections by listing errors in an addendum.
