I understand that. From previous posts I've found that posters have provided me with very helpful tips that eventually lead me to the answer. This is my first analysis class ever, so at first glance I thought that was just what I needed to start with. Then I realized that those two steps implied the answer, so thanks. One last thing if you would be so kind: I thought epsilon was "lurking in the problem," and you couldn't just let it be equal to some answer, or maybe I'm getting ahead of myself?
