.999999...=0!

[DrPizza]

As the titles says,
.999999...=0!

(I'm right, aren't I?)

 

[dighn]

affirmative

Is that the factorial of 0?

 

[Kalvin00]

You are correct.

I believe Dr Pizza is one of those who read at least 90% of the replies in that thread

Nah, I already know the answers...
I was bored as in, "time to continue to sort the morons from the intelligent"

Ahhhh, alkemyst... I see which list you wanted to be added to. 🙂 😛




intelligent +0
morons +0
jerks +1

 

[ruffilb]

Yes, you win.

At life.

 

[bleeb]

I feel you DrPizza, I greatly miss all the NEF posting I put into the original 0.9999...!= 1 thread.

Hey man... hows it going over in ht?

 

[Howard]

Yes, that is correct. Excessive number of 9s, though.

You could always give the Hydrogen thread another bump! 😉

 

[IAteYourMother]

this brings memories... time to bump another thread!!

i am teh suck at math..

but there is nothing that can make me see how <i>ALMOST</i> one equals one.

🙁

No way... that got pretty boring. But, I think we finally convinced whoever it was in that thread (started with "W"?) that hydrogen isn't a source of energy. One person at a time and maybe, eventually, our government won't be full of people with no science understanding. (i.e. our commander in chief)

Well, that's because it isn't almost. It's there.

Hey, at least you got zero factorial (0!) = 1 correct 🙂

i thought .9999999999999999999999999999999........ = 1
so does that mean 0=1? 😕

See the post before yours.


See, KarenMarie... it isn't all that bad 🙂

i hate it when i go off and do something in the middle of reading a thread, lol, i always miss something...

what does .999999999... = 1 = 0! have to do with 0=1? 😕

 

[dugweb]

okay, someone catch me up to speed on the argument, I've never participated in the .999=1 threads before.

The way I understand it is the distance gets so small in .9repeating that for all intents and purposes it equals 1, i guess?

Someone just give a brief rundown on both sides please 🙂

it's not for all intents and purposes; it's not arbitrarily "close" to 1, or even "infinitesimally close" to 1. It *is* 1. As in the exact same thing, just written differently.

There are a few ways to demonstrate it, which are sufficient for all but the most die-hard disbeliever:

.333... = 1/3
.333... = 1/3
.333... = 1/3
add
.999... =3/3 = 1

Or
n = .999...
10n =9.999...
10n - n = 9
9n = 9
n = 1

Neither of these is a proof though. Formal mathematics proofs are a bit lengthier and require a little bit more understanding of some math symbols. Take my word for it though, there are dozens of valid proofs that .999... = 1. There is not one single valid proof which contradicts it.

 

[Tiamat]

all that matters is that in the real world anything within the range [0.5,1.5) can equal 1 depending one the precision of the tools you use to measure.

Debating whether or not .999... is equivalent to 1 is trivial since normal people do not have any means to measure that precisely.

Now, if you were able to deal with things in terms of Planck's lengths, you might have an arguement since no length can exist beyond this precision, thus rendering .999... (or any similar nonterminating decimal) impossible, but only a select few people care remotely about that.
