.9999...=1

If you are referring to me then I know what infinity is already so don't worry about that! ;)

I was trying to say it is hard to demonstrate 1/3 and other kinds of fractions when you are using decmials but no I disagree with you guys when some one says

1 = 0.9999

No I don't think so.

It doesn't to me.

Why has infinity got anything to do with something that should just already equal 1?

Why? :confused:

Anyway! :)

I have said what I wanted to say! ;)

I believe it is not true. :)

I will not change my point of view unless I see something else or someone can show me something may not understand. :)

:D

3*(1/3)=1
3*.333...=.999...

Since 1/3=.333..., .999...=1

QED

Le sigh! ;)

How childish of you EarlyMon! :)

I did not think this of you!

And no!

I don't agree with you at all!

So EarlyMon... you are saying that... things can never change and whatever the flawless scientists say... it is set in stone forever???

Why can't things change???....

Are you saying this so called "proof" can never change?

You did not even look at what i was trying to say!

You claimed I "believe maths terms can mean anything I like"..????

I did not mean that at all buddy! ;)

Sorry! :)

Where did you get that from?

Why can't some one question things????

Isn't this how the light bulb was made and the computer you are typing from???

You do know that the so called "scientists" from 1000's or whatever of years ago "knew" that the Earth was "flat"...

They "knew"...

They were wrong.

Very very wrong.

The so called "top scientists" were arrogant idiots...

Things change... times they change and people they change.

Everything changes over time...

Theories change...... it is how we move forward... and question things... not go backwards...

You did not get what I was trying to say!

I disagree with what you guys are saying and I am cool with this. :)

I don't agree with it... ;)

I have said what I wanted to say and I am sticking to it thanks! ;)

I guess I am like this guy sometimes in this cartoon... awesome cartoon...

[/QUOTE]

No one is saying to not question things. Questioning things is how we improve but mathematics is fairly rigid and has changed very little since the olden times. If I was to go around saying that mass doesn't exist, people would think me an idiot.

With the exception of death and taxes. Two things that do not change. And Daleks :dalek:. No, that's three. Three things that do not change, death, taxes, Daleks, and the Spanish Inquisition.

No matter how far you go (which shouldn't matter at the end of the day) you have to stop somewhere...

It doesn't matter if it goes to the 1 billionth decimal point... you will still end up with a problem.

And it will never equal 1.

This is how I see it! :)

It shouldn't matter going to the 1 billionth decimal place because you still not at 1.

It doesn't matter because you cannot reach 1.

OK, well I'll keep trying. :D
You asked what infinity had to do with it. Well, we are talking about .99999 repeating here. There are an infinite number of 9s.

As the number of nines approaches infinity the number also approaches 1. So the number is getting infinitely close to 1. So at infinity, it will be equal to one. Therefore the limit is one.
 
I totally agree that you will get closer to 1 but you will never reach 1! :)

You will never reach it!

You can go on forever into the end of time but you will never reach 1.

You are right ... you will get closer... but you will not get your cigar! ;)

Yeah, but we're talking about a decimal with an infinite number of 9s. If you cut it off at the 100th or even the billionth 9, we're talking about two different numbers.

That's not how it works at all.

You're making your point clearly.

But that's not how it works.
 
It doesn't matter if it is at the 10th billionth decimal point or the 7th decmial point because according to the bogus proof that was shown earlier.

let me simplify and only use 5 decimals places for arguments sake:

x = 0.99999...

(We are next going to multiply both sides by 10 now because it is a scale and must be perfectly balanced)

10x = 9.9999

(Now there are only 4 decimals after the 9 and the original x has fiveb decimal places and not 4....)

(Now we subtract x or also known as 0.99999 (FIVE decimals because we need to subtract x (because this is the real x) from both sides)

10x - x = 9.9999 - 0.99999

(9.9999 - 0.99999 = 8.99991)

(Do you see where this is going now?)

now:

9x = 8.99991

Now they say they want to just divide by 9 okay cool lets do it:

9x/9 = 8.99991 / 9

x = 0.99999

(This is exactly where we left off and we have not done anything fancy at all and have gone no where and have still not proven anything still and this is 1... nothing has changed like they want you to believe...)

You still do not get 1.

No matter how far you go you will never get 1.

You will get closer but that does not mean you get 1.

It doesn't matter if you use the 10000 billionth decimal or the 10 decimal place or even the 5th decimal place because it still does not prove it at all.

But what does matter is that you keep x constant and you decide on a point of the decimals and stick to it.

It does not matter where on the never ending list of decimals you go to... because you will never reach 1.
 
It has to end somewhere.

It will have a fix amount but measuring the exact distance would be very hard.

But when you are dealing with theory like going on into infinity with imaginary numbers then that is a different story.

Very true that it goes on forever.

You can never stop counting for example.

But when dealing with size or distance it has to end somewhere and somehow.
 
it is interesting to see how this discussion has taken so long.
lets take small steps..together.

things we all should be able to agree on:
"..." = infinit repeat of that last digit
1/3 = .333...
if you take a number (N), then divide it by X,
N/x = y
then take the result and multiply it by X, you get N.
Y*x =N
example: 10/2 = 5; 5*2 = 10 or 1/2 = .5; .5 *2 = 1
this is a very set and solid fact.

so then it is true and fact that:
1/3 = Y; Y * 3 = 1
therefore:
1/3 = .333...
.333... * 3 = 1

but what is .333... * 3 = ???
.333.... * 3 should equal to .999...

so here is what looks like
1 = (1/3) *3 = .999... = 1

at what point of these small steps.. did you get lost?

Well I am glad you got what I was trying to say! :)

Can you explain to me why in some kind of way?

1 = 1

And not 1 = 0.999999999999999...

This is not 1.

I may sound like an insane crazy nit picky ass hake but it's the truth.

You will always get closer... but you will never reach one.... you will get closer but never reach it. Ever.

Anyway! :-)

Shaw I am tired and bored of this conversation now! :)

I have tried to explain and I now need to move on and sleep! :D

I am tired now hehehe! :D

Dan I am not lost! ;)

If you take 0.333... running off into the distance and you times this by 3 you will not get 1.

What I was trying to say is that when we write a 1/3 into decimal notation we begin to struggle because there is no concrete way to simply show 1.

What I have been trying to say is you can't write in decimal notation when dealing with a 1/3.

And many many other fractions.

If you write:

0.33333334

And then:

0.33333333

And finally:

0.33333333

You will get a whole or 1.

But these are not each a third... they are not all the same this is just what I was trying to say! :)

This proves how you can't write it in decimal notation to get 1! :)

It is just 1 of those funny things in maths! ;)

This is all i was trying to say! :)

Good Lord I am stuuffed noe!

xD

njeed to sleep! :D

Yes.

It is.

You don't believe it.

You don't have to believe it.

Just like you don't have to believe that the French word for yes is oui.

But that doesn't make you right.

As long as you're not open to any new ideas here, you're not going to change your mind.

You're not following the proofs as presented.

You're substituting counter points to make your case.

That's called voting.

It's not up to a vote. :)
 
stinky...

you are lost at "..."

1/3 = exactly .333...
that is 100% truth.

same as 1/4 = .25 and 1/5 = .20 and 1/2 = .50 and 1/6 = 1666...

to help students to learn math.. we might simplfy things.
1/3 = .33
1/6 = .167
but that is NOT correct!!
1/3 = .333...

But 1/3 is exactly 0.333333333... Continuing on into infinity. If you agree with that...

(1/3) * 3 = 1

Could be replaced with:
(0.33333...) * 3= 1

Could be written another way (3 * 0.333...)
.:
0.99999.....=1
