    I've a question: is 0.(9) the number 0.9999 followed by an infinity of nines or is it the limit of that? If it's the limit then it's equal to 1, if not, it's not 1.

    The limit of what?

    Yes, semester.

    I was taught that 0.9_ equals 1 by my math professor also.

    You see, the 0.00...01 number itself is not there. There's no such number. There's a reason It's called repeating number. You starts with 0, you ends with 0. My professor basically use it to somewhat prove 0.9_ equals 1.

    the limit of "the number when the number of nines goes to infinity"

    basically (maple syntax) limit(sum(9/10^n,n=1..x),x=infinity);

    If its a number, its not a limit

    But yes, i meant 0.(9) = limit(sum(9/10^n,n=1..x),x=infinity);

    ah ok, then it's a limit. I thought it was just zero dot infinity of nines. but yeah if it's a limit then it's 1 because limit(sum(9/10^n,n=1..x),x=infinity) = 1

    by the way in this case the limit is a number. did you expect a matrix or what?

    It's the same as zero dot infinity of nines if you write down limit(sum(9/10^n,n=1..x),x=infinity) you'll se it is.

    Why would i expect a matrix?

    Seeing that this basically pans out to be a <a href='http://www.unknownworlds.com/forums/index.php?showtopic=73551&st=135' target='_blank'>double thread</a> (posted by the same person, no less), I'll go ahead and <span style='color:red'>***lock***</span> it.

    To add to Nem's comment, the above link is a good one to check out. In mathematical theory, yes, 0.(9) does equal 1.(0). In the real world, as you cannot measure 0.(9), the two are effectively different numbers.

    As others have said, 64 != 65. The image is an optical illusion and the imprecision of the angles can be seen if you look closely.

    As for this,

I did not make this thread to discuss if 64=65. I made it to talk about 1=.99. If you notice, in my first post I had said that everyone agrees that 1=.99. This was bound to upset some people, and make them start talking about that thread instead, which is much more interesting and fun to watch people get angry over.<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->

    Do it again and you won't.
