ok, so supermum is the least upper bound, but when you write down on paer, what am I trying to show...does that make sense? I mean, what am I trying to get to that will show something is the supermum.(adsbygoogle = window.adsbygoogle || []).push({});

so for example: prove sup {1 - 1/n} = 1 for all n in N.

so I start by saying that I know that 1 is an upper bound.....

then, for all epsilon > 0, there exist n st n > epsilon, or 1/n < epsilon.

ok, now what....how else do I need to go to show that 1 is supermum...

how do I know that I have shown that 1 is the supermum??
