The limit (360 - v) really could be 0 if perfect flatness is allowed,
but when we add the constraint of curvature, then even though
everything locally seems to stay the same -- given the epsilon / delta
treatment alone (Debater A) -- the added fact of curvature is new
information and tells us that as n --> infinity, there's a 720
involved (Debater B).
1. You don't have to allow flatness. The limit(360-v) is indeed 0. It is a limit. The function doesn't have to actually get there.
2. The limit(n*(360-v)) is indeed 720, and again, allowing flatness is not an issue.
3. Now state your contradiction.
