Yes. Thank you for asking.

I guess I'll just play with some sin functions with a limit of 1 see if I can prove it with epsilon delta. I'm just still a little confused with epsilon delta. Thanks for the tip

Suppose , and at least for x in some neighborhood of a. Then given any , because , there exist such that if , then . Because there also exist such that if , then . Of course, it is true that if , then . But that means that if |x- a| is less than the smaller of and we must have . Can you finish from that?
