@miracle173. Thanks! (btw, if I remember correctly you can add invisible html comments <!-- --> to bypass the edit size limit if you need to fix typos in the future)

comment Help with epsilon-delta proof of continuity
eps-delta is traditionally hard because it is one of the first times you encounter a statement with nested exists and for-all quantifiers. The problem is that unless you can specify a specific problem you are having I don~t think anyone here will come up with an explanation that is much better then the one in your textbook.
