Re: .999~ = 1
alright i thought of a different way to prove that .999...=1
first we have to prove that if (X+Y)/2=X or (X+Y)/2=Y then X=Y
this is simple
(X+Y)/2=X
X+Y=2X
0=X-Y
Y=X
alright now we move on
1 (.9999...+1)/2 ?= .999...
2 (1.999...)/2=
3 .999...=.999...
now you might be thinking: "whoa...how do you get from 2 to three...that looks crazy"
well 1.9/2=.95
1.99/2=.995
1.999/2=.9995
so 1.999.../2=.999...5
however i have given all you non believers false hope with that last 5
1.999.../2=.999...
because the nines will go on FOREVER, they wont stop, so that five does not exist the five never happens because the nines never stopped...thus .999...=1
