Ok, I'm finishing my AA at a state college this semester and transferring to a university for fall. One of my friends who already transferred told me I need to learn about sequences and infinite series (though I haven't been able to follow up with him since). For some reason, our calc teacher that instructs calc II & III never covers it. I did learn a bit about MacLaurin and Taylor's formulas through OCW, but I really don't know much beyond the general idea of them. I haven't used them in problems or any of that, but I'm not sure how much I need to learn at this point? Does anyone have any decent sources for material I should know by the time you finish calc II (multivariable calc)? I want to learn it but I already have so much on my plate that I don't want to go overboard and have it cut into my other studies. While we're at it too, how important is linear algebra? I know it is a preferred course for most grad schools and I saw some OCW for it, but I haven't had time to look at it yet. Will it be useful at this point or should I just wait until later when I can take it as an actual course and put my time into other studies?
