However, I plan to approach the basic concepts of calculus using infinitesimal differentials, because this is easier and closer to the way calculus is actually used, compared to the approach taken by the textbook (which is based on limits). A nice textbook that takes the same approach as I do is Calculus Made Easy (Silvanus Thompson, 1910), which you can read free online (although the language is a bit old-fashioned and British).
I also have some notes for lectures, hand-outs, and so forth. If you missed class, then you might be able to find a substitute here. But there is no guarantee that everything will show up!
