1/3 * 3 = 3/3 = 1 1/3 = .333333333... .3333333... * 3 = .99999999... so .999999... = 1?

Actually, I think it does.

Yes, it definately does. There are other ways to prove it, also.

EDIT: Reffering to 0.99... = 1, of course.

Thats what my math teacher told me. kekeke

0.99999.... = 9*10^(-1) + 9*10^(-2) + 9*10^(-3) + ...

= Sum from i=1 to inf of (9 * 10^(-i))

= 0.9 * (sum i:0->inf (0.1^i))

= 0.9 * 1 / (1 - 0.1)

= 0.9 / 0.9

= 1

Pouya''s proof pisses me off, therefor, 0.9 repeating = 1

I disagree. 0.999999999999.... is 0.00000000000...1 less than 1.

Please explain to me how that 1 at the end would ever be reached?

It can''t. Welcome to infinity, or as I like to call it "1/0".

Dammit, man - are you a man or a cow. Oh wait - cow is in your name, but I just called you a man. Holy pretzels, I''ve gone crosseyed...

Anyway, here''s the proof you seek:

STEP 1: physically enlarge and pixelate left hand side of the equasion:

100
100

STEP 2: add imaginary line to the left hand side of the equation

100
---
100

STEP 3: evaluate the left hand side of the equation

100
--- = 100 / 100 = 1.0
100

STEP 4: compare the left hand side of the equation to the opposing right hand side of the same equation

1 = 1

Q.E.D.

Actually this works best if written by hand on paper - what you witnessed above is he effect of digital degeneration

.3333333333333 etc is an approximation for 1/3, and not actually 1/3.

While 0.3(3) is not.

Quoting the book Real Analysis 3rd ed. by H.L.Royden
Page 40, #22:
quote:

Let p be an integer greater than 1, and x a real number, 0 < x < 1.
There exists a sequence <an> of integers with 0 <= an < p such that x = Sum n:1->inf (an / pn) and this sequence is unique except when x is of the form q/pn, in which case there are exactly two such sequences.


For those of you who don''t get what I just quotes, the sequence an is the decimal expansion of a number when p=10 (base 10) and when a number is of the form q/pn (i.e. a "special" rational number whose denominator is a factor of some power of 10) then there exists two such expansions in decimal form for the number, one being the finite representation of the number, and the other being an infinite series summing up to that number.

In this case, 1 is 1/1 = 1/(10^0) is of this special form, and thus there exists two decimal representations for the number, namely 1 and 0.999999....

Can it really be proved that 1/0 is infinity? I thought not.
