yeah, I mean it's simple enough for you to understand...

Actually that doesn't equal 1. .9999... (repeating) does though.

.9999999999999 = .9999999999999 :P

Read my posts. There is no difference. There is no 1 at the end. It's infinately many 0s, which as jimerax said, is equal to 0.

altairian · 01-11-2004, 10:50 AM

aleco, sorta, but you have to realize there's an infinite number of zeroes in front of that 1, so basically that number is so small that you might as well forget that 1 is even there and just call the darn thing 0.

jimerax, like I said before, you could never ever prove that an infinitely small number is equal to zero.

makaveli, that explanation sucks

A number divided by itself can never equal anything other than 1, so you cannot say that 9/9 = .999 repeating

Yeah, I figured that out but I was away so I couldn't edit it, sorry.

Unless .999 repeating = 1

banditcom · 01-11-2004, 09:24 PM

And there is no 1 at the end of the infinite zeros.. there is no end. :P

It needs a definition to prove this.
And this is a definition of limitation, so no more proof is necessary.

For all cases we assume .999 is .999 repeating

x = .999
10x = 9.999 repeating

10x - x = 9x
and
9.999 - .999 = 9
9 = 9x
1 = x

This shoulda been at the beginning

haha banditcom I suppose you're right.. =)
Just trying to help aleco out hehe

uh, limits are different. Limits say "this function approaches this number at this point". There's really no actual equality in a limit, when you use an equals sign when solving a limit problem, you're saying "the limit equals this".

Yep.
