Trolling ends here

OH HEY, THIS THREAD LOOKS COMPLETELY LEGIT.
>>1084422 THIS GUY SAID IT WAS COOL

oh man i am so going to rage right now because his art sucks.

I hate soccer and that 1 is being a very bad goalie aginst those 9s kicking the ball into the goal.

Art sucks take it somewhere else

sage

>>1084429
you now see the 9s kicking the decimal ball

OP, one does not equal .9999. It equals .999...

The ellipsis represents an infinite series of digits preceding. So, .999... is .999 followed by an infinite series of nines.

The reason you can generally consider the two values equivalent is due to the mathematical concept of limits. The limit as n goes to infinity of .999... in this case is 1.

4 sages and a pathetic attempt at a 5th. /sci/ is learning?

>>1084496
WHY ARE YOU REPLYING TO A TROLL HOLY SHIT
YOU MAKE ME RAGE HARDER THAN THE OP

>>1084557
To make you rage, why else?

In number theory between any two distinct real numbers there are other real numbers. There are no numbers between 0.999... and 1. Think about it. If you assume that a number "x" exists between 0.999... and 1 then you can add some value to 0.999... and the sum would be "x." But, where in the infinity of 0.999..., can you add a positive value without the sum falling above 1? Nowhere. 0.999... is infinitely close to 1. Number theory says they are the same.

>>1084495

I like how, in order to prove that an infinite number is rational (i.e. exact), you're assuming that the rational (1/9) can be represented in an infinite notation (series).

Ever heard of circular reasoning?

Of course you haven't. Learn some math, and logic, faggot.

>>1084849

This. People who don't know shit about math are using the same circular logic to prove 0.9r = 1

0.9r will never be equal to 1. It will always be slightly less.

Explain it with fractions. That always makes it easier.

HURR DURR

good lord /sci/ is terrible

itt people who flunked analysis

>>1084889
>Has no idea what analysis is and never took it.

>>1084506
Didn't check the sages did you? Hint: one wasn't sage

>>1084867
Hi Mr/Mrs Troll. Did you know there are better ways to do it so that isn't a problem? see http://qntm.org?pointnine for all your proving needs.

>>1084932
FUCK I DIDN'T SAGE MYSELF

sorry for bumping a troll thread guys. I just couldn't stop myself from replying.

>>1084396

1 /= .9999
1 = .999...

It might not satisfy your typical /sci/fag but I look at it like this:

How much less is .999... then 1.

You might be tempted to say .0....001 or some such, however no such number exists, you cannot have at 1 at the "end" of an infinite chain.

>>1084959
>some such

>>1084997

Don't look at me like that, I didn't bump the fucking thread.
