Perhaps it’s been a while since you’ve needed multivariable calculus, and you’ve forgotten parts of it. That’s fine. Except that during your MARC hours students are bombarding you with Calc 3 questions, and they’re starting to suspect you’re lost when you keep restating their questions back at them. Don’t fear! During this talk, I’ll attempt to cover the highlights of Calc 3 and frequent problem areas for students in the MARC. Since our goal is to be of maximum help to MARC students, we will focus on doing examples and sweep most theory issues under the rug.
