I got this textbook early, to study over the summer before classes this fall. As a consequence I don't have any teachers or fellow students to consult, mainly in terms of checking the validity of my proofs. All I have is this forum. So, I apologize if this thread question seems exceedingly redundant, but consider this: even the slightest of differences in a specific problem, at this premature, introductory level of epsilon-delta proofs, the level that I'm at now; even the slightest difference can bring cause for personal concern, or a disconnect in the neccesarry understanding of the proof involved. I'm sure that to most people on this forum, the two posts I've recently made about epsilon-delta proofs will probably seem incredibly alike. But just understand that even with the simmilarities involved, I still wasn't certain that my proof was valid for this simmilar problem. I'm still just learning the basics of epsilon-delta proofs. I'm not trying to be some annoying, double posting idiot. I'm just trying to do my best to get ahead of learning this stuff before fall, and this forum is my only resource as of now.
