Hey all, So I took calc 3 back in 2004 actually, and though I've taken a couple of classes since then, (diff eq, complex variables, some physics, etc...) I haven't taken ANY math or science class in about 5 years. So I start this fall with Calc 4 and I'm trying to review a little from my old books. I don't have tons of time for review, so in your educated opinions, which topics would be the most beneficial to review before Calc 4? I'm brushing over some basics, the fundamental theorem, basic integrals and derivatives, and reviewing some trig identities, but I know there's so much I've forgotten. If you were going to focus on say 2 or 3 calc topics in order to prep for calc 4, what would they be? Or maybe brushing up on calc is less important than say, trig or algebra or even geometry. I know I'll have a lot of work to do this fall, but basically, when I walk into class I just don't want to get lost immediately from being too rusty on the basics. So what do you think would be good review? Or at least very necessary topics to be familiar with? Thanks!
