\(\displaystyle .\dot{9} = 1 \). Right?
I think Denis was trying to disallow \(\displaystyle .\dot{9} = 1 \) in his little number game on another post. (You know the one!)Cat, I know you knew this fact. So what exactly are you really saying or trying to do? Is it just to annoy Denise? I thought that was my job.
Actually I don't, I'll look now.I think Denis was trying to disallow \(\displaystyle .\dot{9} = 1 \) in his little number game on another post. (You know the one!)
Yeah you do. You were roused on a few times!Actually I don't, I'll look now.
\(\displaystyle 0.\overline{9} \ \ \) is sufficient for the number of nines.Yes. There are many, many proofs of this, but one I prefer is to think of it in terms of a series.
\(\displaystyle 0.\overline{99} = 0.9 + 0.09 + 0.009 + \cdots = . . . \)
