0.9999... = 1?

Re: 0.9999... = 1?

1/3 ~ 0.3333..... and
1/3 ~ 0.3333333333333333333333333333333

the bar above the numbers means extend to infinity.

with that being said, dun just be a fucking idiot.

I am sorry but
the chart shown cannot be consider any reputable source as Sloth said, i can make one too in 2 min

Re: 0.9999... = 1?

u are just keep flaming without any logical prove to ur own arguement, here i provide another prove, its simple Geometric Progression (G.P. )

click here G.P. formula
if u forgot the formula, actually i have forgot it too

0.9999..... = 0.9 + 0.09 + 0.009 + ..... = 9/10 + 9/100 + 9/1000 + .....

Sn =

a = 0.9, r = 0.1

Sn = 0.9*(1-0.1^infinity) / 1-0.1
= 0.9/0.9
= 1

You cannot use the substitution property if something is approximately equal to something else, IN ORDER TO SUBSTITUTE ONE THING FOR ANOTHER THEY MUST BE EQUAL. You don't need calc 2 or 3 equations when you cannot get past a simple algebraical proof.

all of that work was for nothing. = does not mean ~

and just because something extends infinitely does not mean it automatically rounds to the next number

all equation are EQUAL, unless u dont think 1^infinity is EQUAL to 0 which is agreed by mathematicans

all of that work was for nothing. = does not mean ~

and just because something extends infinitely does not mean it automatically rounds to the next number

We are talking about 0.999.... NOT 0.999...9
it doesnt round to next number, becoz they are EQUAL,
otherwise pls find me a REAL number thats between 1 and 0.99999....

.999 doesn't equal 1, but .999... sure does.

Re: 0.9999... = 1?

Another way of saying this is:

Tour EXACTLY 5 meters from a wall.
Everytime you move torwards the wall, you can ONLY move EXACTLY 50% of the distance between the wall and you.
EXAMPLE. 5 meters away/ first move -->2.5 meters away/ second move 1.25 meters away...

Will you ever touch the wall?

Is that why math scholars argue it all the time because they can't grasp simple rules of math?

I believe they argue it because its one of the few things left unexplained in math. Everything is already mapped out. Math is and always will be the same. Be it base 10, base 88, or base .99999...!, 1+1 will ALWAYS equal 2.

Thats the funny thing about infinity, some believe that it stretches out in a perfect straight line forever, others believe that because our existance is relative to what we can precieve, that it must loop around and start at the begining ofall things known.

Commonly people who believe that infinity is a circle, tend to view that .9 repeating equals one. While people who believe that infinity goes in a straight line extending forever, tend to beliebe the opposite that .9repeating =/= 1.

I on the otherhand do not believe in infinity and believe that EVERYTHING comes to an end.... ...eventually. It is my belief that the only thing thats even close to infinate is time itself. But even that will die when theres noone around to believe in it.

.9 repeating does NOT equal 1. It i absurd to think otherwise. You can add .1 repeating to it and Im pretty sure that THAT is equal to one. Either it equals one or it equals infinity because is it even possible to have a .(10)(10)(10)(10)(10)(10)... ???

Proof

Let x=.999...

10x = 9.999...
- x = .999...
9x = 9

x = 1

.999... = 1

 

[Pepe']

Re: 0.9999... = 1?

Let x=.6!

10x = 6.6!
- x = .6!
6x = 6

x = 1

.6! = 1

That works too, does that mean that .6! equals one also?

WTF lol

it take me 30 mins to realise this lol
10x - x = 9x NOT 6x

lol, i was about to point that out to.

Furthermore the end all be all argument ender to this question is that if .9 repeating isn't equal to 1 then what number is inbetween the two.

There is no number between them, it's .999 continuing to infinity. Or, you could say every number after whichever 9 you stop at in .9999999999999 is between that number and 1.

Either way, numbers in mathematics are variables. Assuming that .99999 etc is equal to 1 is an assumption that many mathematicians agree on. This is similar to the "95% or greater = fact" that applies to the scientific method.

These are assumptions that need to be true in the system of belief called mathematical science. All believers follow the assumptions, and all disbelievers use the assumptions as launching points for their disagreements.

Best poll ever. Might as well be 1.

might as well be, but isn't.

no one in this thread is going to prove anything to anyone. you're a bunch of idiots trying to look smart on the internet

I think it's funny that you took a position on the issue but also decided to dismiss everyone else who did as well as idiots. Maybe next time you find yourself in this situation, just stick with the insult and nix your own opinion.

If you round to the nearest one it = 1.

Re: 0.9999... = 1?

well .9999... could be considered ellipsis notation thus meaning the number continues on forever. Perhaps to a googleplex the one with like 1000000 zeros!!! OMG NUMBERS YEA.. They get me so excited......
