MATH 158 - Calculus III

Gauss

Stokes

Suggested Textbook

I will refer in my lectures to the following freely available textbook:

• J. Marsden & A. Weinstein, Calculus III, Caltech
• J. Marsden & A. Weinstein, Calculus III Students' Guide, Caltech

Since Calculus III did not change in the last century, you can study instead from the Stewart's textbook if you like to. In fact, I do suggest you all to study from both of them since being exposed to a different point of view is always very good! If you like I list below a series of alternate free textbooks you are also always welcome to consult.

Homework

Graded Homework will be assigned weekly on Webwork.

I will usually provide you a short list of ungraded homework from the suggested textbook. While Webwork problems will usually be straightforward problems, these ungraded ones will be usually harder and are more meant to make you think more about and understand more the topics of the corresponding sections. The list of those problems is in the lectures log below.

Video lectures

Here are a few series of very well done Video Lectures you might use in case you feel the need of hearing more about any of the topics we are going to cover:

• Calculus 3 Lecture Videos from University of Utah
• Calc III Video Lectures from MIT
• Michael Hutchings, Multivariable Calculus Video Lectures, University of California, Berkeley
