Goal: Trig re-learned by Monday.

I am taking Calculus, which is kind of awesome. However, I have a bit of a problem. I need to have basic functions and identities of Trig memorized by Monday, and I haven't done any Trig in 4 years. I've been looking at the functions and identities as listed in my book, and all it's doing is giving a vague sense that somewhere in my brain I know what Trig does, but I can't quite call it up.

Does anyone have advice on resources to help me quickly refresh my memory of Trig? A website giving a basic rundown of how it works would probably be good enough to jog my memory. The problem I'm running into right now is that I'm given problems such as "find the limit as x approaches 0 of x^4cos(2/x)" and I can't figure out what to do with a cosine being involved. I get limits, and x^4 is no problem, but I stare and stare and poke and poke my brain to no avail trying to reveal something in the depths of that little "cos."


I'll give you an e-cookie. ^^''
