If you didn't understand then why didn't you just say so?
Do you understand that your contradiction is essentially between limit(n) * limit(720/n) as n->infinity and limit(n*720/n) as n->infinity?
Do you understand that the left side of that comparison is the part that is not valid, that limit(n) as n->infinity does not exist?
You may have meant something else, but you never stated the contradiction explicitly. You just said, how can these somethings go to zero yet if you add them all up they add up to 720. Translated to something explicit, that becomes limit(n) * limit(720/n) as n->infinity.
