Course Goals

In this course we will extend our theory of calculus to cover functions of multiple variables. We will understand these functions algebraically and geometrically, and learn how to use the tools of differential and integral calculus to further understand them.

Topics will include: 3D graphing, planes, partial derivatives, vectors, directional derivatives, gradients, the chain rule, optimization and Lagrange multipliers, integration, parametrization, vector fields, line and surface integrals, and Green’s, Stokes’s, and the Divergence theorem.

The course syllabus is available here.

Graphing calculators will not be allowed on tests. Scientific, non-programmable calculators will be allowed. I will have some to share, but not enough for everyone.

Edfinity online homework system

We will be using Edfinity for Math 2233-11. To enroll, please follow the steps below:

  1. If you already have an Edfinity account from a previous course, please sign into it. Otherwise, go to step 2.
  2. Go to the following registration link:
  3. You will be prompted to pay (I believe the fee is $25) and enroll in our section.
  4. Start working on your assignments :)


The official textbook for Math 2233 is OpenStax Calculus Volume 3 by Gilbert Strang and Edwin Herman. It is available for free online here. You can also buy copies from Amazon; a paperback is a little under $30.

I will be loosely following the textbook, but will often be giving my own take or focusing on topics the textbook doesn’t emphasize. All my course notes will be posted to the course web page.

This section of Math 2233 will use the Edfinity online homework platform. You will need to buy a license, which I believe is $25.
