Well, limits have been the hardest thing and most confusing thing for me to learn. I hope I end up understanding them.
Top three problems:
1) How do you find the limit of infinity if you don't know how to graph it?
2) How to solve a limit with sin or cosine or anything like that.
3) Graphing trigonometric functions when there is more than just a variable.
Well I hope I understand it better soon.

I can help you with your issue #1.

1) GO DENISE! =)
ReplyDelete2) If you're looking for the limit of sine and cosine, it's usually written with something else, right? If you can find a (sin x)/x, go with that because that you know the limit as x-->0 or as x-->infinity. Other times, if you're looking for the limit as x-->constant, then you can just try plugging it in. For x-->infinity, sine and cosine alone don't have limits, but compared to other x's that grow infinitely, you can treat sine and cosine as 1.
