The Unit Circle

[seductivenerd]

I know that the unit circle is soooo Pre-calculus, but it's causing me problems in my calculus class. There'll be questions that expect you to know the coordinates at a certain radian and what not. Are there and tips, tricks, etc, that you all can give me in remembering/learning the unit circle? I mainly need help with sectioning it different ways

Is this the sort of thing that would help you? (you could print it out)

I found them by googling "Unit Circle" and then clicking on "Image Results for Unit Circle" and there are a lot of them on the web.

Of course there are copyright issues if you just take one. But if you're only using it for your own personal use, it's probably 'fair use' and legally okay, and if you wanted to give a copy to someone else, you could look for a website that says it's okay to reproduce.

(At the end of the day they're all the same thing, so the copyright issue is a bit unclear).

If that doens't help, I'm sorry for misunderstanding you.
