Welcome to the home page for section ES31 of MATH-1400 (Applied Calculus) at Southeast Community College in the Spring term of 2013. I am Toby Bartels, the instructor.


Here are some useful links for the administration of the course:


If you miss a homework assignment, then you can find it here. Eventually some solutions to graded homework will show up here too. Although only homework and the final exam contribute directly to your grade, attendance is also important.


The official textbook for the course is the 12th Edition of Calculus for Business, Economics, Life Sciences, and Social Sciences published by Prentice Hall (Pearson). You should be able to get this at the bookstore, and most homework problems will come from it. If you pay for it, you can also use MyMathLab with Course ID bartels48875; this is optional.

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 lecture notes, hand-outs, links, 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!
