It's mainly designed for those who want to teach at a junior college or whatever. I plan to stay in oil and gas, and I'm going to take:

I'm not concerned about analysis, because I did well in undergrad and have a strong interest in it. However, I took Cal III in 2008, so I'm a bit rusty in it. I do have my calculus textbook. What, specifically, should I review to prepare for the differential geometry class? Moreover, there is no assigned textbook; the professor will provide the notes. What's a good differential geometry textbook that I can use to supplement the class? Thanks.

Spivak is good, but it consists out of $5$ volumes, and the first volume is not relevant to the contents of your course. So you'll have a lot of reading to do to actually get to what your course covers.

The standard reference is Do Carmo, this is a very good and leisurely book. https://www.amazon.com/Differential-Geometry-Curves-Surfaces-Manfredo/dp/0132125897

A very good book and quite easy is Pressley: https://www.amazon.com/Elementary-Differential-Geometry-Undergraduate-Mathematics/dp/184882890X It also contains the things you need to study without much extra fluff.

Another of my favorite is Bar, but this does have a very severe lack of exercises. https://www.amazon.com/Elementary-Differential-Geometry-Christian-Bär-ebook/dp/B00AKE1X8E

Especially multivariable differentiation is important here. Know what partial derivatives are. You should know the chain rule cold. Know theorems like when you can switch partial derivatives, etc. Be sure to know what a Jacobian and a Hessian is. Knowing how the general derivative is a linear transformation is good. If you have seen the inverse and implicit function theorems, then be sure to understand those well. The multivariable Taylor theorem can pop up occasionally.

Theory like multivariable integration and vector calculus seem to be less important for the course you're going to take. But you should definitely be able to calculate (multivariable) integrals and derivatives.

Series are not important. Sequences are also not important.

If you mention a topic here, I can tell you whether it's worth revising or not.

Thanks. The Spivak collection appears to be a bit much for me, though. I forgot about the MIT online courses! Heh.

Thanks. I think the Pressley textbook is most appropriate for me, as the class is probably just a very basic introduction to the material. I suspect that most of the designated classes for this program are this way, which is precisely what I want. I don't intend on getting a Ph.D in mathematics or doing research. However, I will personally enjoy learning more mathematics beyond my undergraduate education.

Great. I actually did well in my Cal III and Vector Analysis courses, so most of the aforementioned topics are already familiar to me. I'm not familiar with the Hessian, though.

It's just the determinant of the Jacobian

I looked up the Jacobian in my calculus textbook, and it is simple when making a transformation with a single integral, e.g. x = g(u), dx=g'(u)dx. I tried to figure it out for the case involving two integrals - x=g(u,v) and y=h(u,v) - but couldn't make sense of it. The notation for the Jacobian is a bit strange: partial(x,y)/partial(u,v). It makes more sense in my vector analysis textbook where they derived the Jacobian for a linear transformation.
