Math 2

are you aware that 0.99999999 repeating is equal to 1 ? watch this
say that o.999999 repeating equals x
10x = 9.9999999999 repeating
subtract 1x from both sides and you get
9x = 9.000000000divide both sides by 9 and you get
x = 1
weird huh?

no,
if you subtract 1 from 9.9 repeating, you get 8.9 repeating.

Yeah that is neat. One of those counter intuitive math things that doesnt seem right but is. =p

It’s kind of like the thing where you can get 1=2. I forget how that went, but I’ll see if I can’t figure it out again.

Yes, they are equal. It’s like saying the limit of 1x as x approaches 0 equals 1.

Let x=y, then
xy=x^2
xyy^2=x^2y^2
y(xy)=(x+y)(xy)
y=x+y
y=y+y
y=2y
1=2
:lol:

Well…
1/9 in decimal is 0.1111…
Thus, 0.999… is 9*1/9 = 1
not too suprising@Dirt:
Let x=y, then
…
y(xy)=(x+y)(xy)
y=x+y
…The good old “divide by zero” trick
nice is alos when you use only the positive solution of a square root and forget about the negative one.

I didn’t forget, I just…decided not to include it. Yeah. :roll:
