I think all that needs to be shown is that for any positive x, there exists a member of the described set between 2/3-x and 2/3. The proof is left as an exercise for the reader.

Off-topic discussion. Wanna talk about corsets, duct tape, or physics? This is the place. Detailed discussion of any current-season TV must be whitefonted.
Oh, okay. Using that definition, I think it does work. I was looking at
If a property M does not belong to all values of a variable x, but does belong to all values which are less than a certain u, then there is always a quantity U which is the greatest of those of which it can be asserted that all smaller x have property M
and not getting it. Although now I look at it... I guess it does say the same thing. It was that "a variable x" that was confusing me. Thanks, guys! Now I have to attack Dedekind cuts and paradoxes. My brain really isn't up to this stuff.
Let A be the set of numbers in (3/5,2/3) that have decimal expansions containing only finitely many zeros and sixes after the decimal point and no other integer. Find the least upper bound of A. (prove your answer)
My head hurts, and I can't help but wonder what is the practical value of the question. Good luck.
Can't help you there. Dedekind cuts always made my brain hurt. Good luck!

Practical value? Did you miss the part where I said History of Math? Practical, shyeah! I do homework on things that were proved impossible 500 years ago!
God I'll be glad when this class is over. The homework just never gets any easier.
Mooooooooom I think they're talking math again.

BWAH! This one is getting passed on to DH.
I shouldn't mention how often I like to consider different approaches for trisecting the angle, huh?

No, no! Not really! This is history, see? The people who wrote this stuff? All dead!

You're a rebel, and you'll never ever be any good.
So remember how the whole breaking-stuff-that-used-to-work in my apartment started with my computer freezing up? It just happened again. The computer freezing. It wouldn't even turn itself off by the button, I had to manually unplug it from the electricity.
I'm afraid to go home to see what else was broken through that, just for completion sake.
