I think I'm getting better at grabbing a whiteboard as soon as I walk into class. One thing I can't remember is the derivitives of cos sin tan cot csc and sec. I can remember that d/dx Sin=Cos and d/dx Cos=-Sin, and I think d/dx Tan=Sec^2 and maybe d/dx Sec=SecTan. I can't remember anymore than that though. I'm not sure why position=S(x), velocity=S'(x), acceleration=S''(x), and jerk=S'''(x). What does jerk even mean? Will we get into this later? I think I understand the Chain rule, but the worksheet that was handed out today (10-18-13) about composite funtion integrals just baffled me. I can follow what the sheet asks, but I feel like I'm doing it wrong; please explain it on monday. Nevermind, I just watched the video we were supposed to watch yesterday, and it answered every question I had.
