Can someone give me a quick lesson on solving for the limits of trig functions. my teacher didn't do a very good job of it, and she expects us to take a quiz after the first day. i'm in so much trouble, so if someone could help
This is a bit too vague I think. There's quite a lot of material I can think of that has to do with trig limits.
Here's a link that covers two important special limits, with some examples:
