Infinity * Zero = Any Number ARGUE HERE

Re: Infinity * Zero = Any Number ARGUE HERE

Anything multiplied by 0 is 0.

Therefore, Infinity*Zero is 0.

Anything multiplied by infinity is infinity.

Therefore, Infinity*Zero is Infinity.

im sorry math doesnt work that way
ps i am mocking guido

It is called precedence, not "rule of dominance."

Guido is correct...

yeah i had a brain lapse and i couldnt think of the word i wanted to use.... more like a brain fart really.. but any ways thats why i put the "quotation marks"

Re: Infinity * Zero = Any Number ARGUE HERE

You are also mocking the wrong person.

Where is this thread going? Infinity x anything = undefined. It is math...

No I am well aware of who made each post.
I was mocking the fact that chrissi was mocking me and actually mocking guido simultaneously... it was a lil funny to me i guess
All the equations deemed undefined will never be defined an there fore useless to argue about unless some sort of new process of thinking is deemed appropriate such as precedence of rules

Hey guys.

Inf = Inf/1
0=1/Inf

(Inf/1)(1/Inf)=1

If you don't believe me, try taking the limit as x approaches infinity of 1/X.

And the Inf=Inf/1 goes without saying.

And here's what happens when you expand it.

0 = lim (y/x) , -inf<y<inf
X->inf

That way Inf*0 = {all numbers except inf}

Re: Infinity * Zero = Any Number ARGUE HERE

1/infinity and infinity/1 don't make any mathematical sense.

Sure, any number divided by one is itself, but does cat/1 mean anything, mathematically? No.

Infinity is a concept, not a number.

Zero is not equal to 1/inf.

1/inf APPROACHES zero.

Even I with my limited knowledge of math know this much. Your entire beginning premise is false. Therefore I don't even have to read on to know that your proof is wrong.

the fact that chrissi was mocking me

Not unless you = moches... :\

haha oops i didnt read who you were quoting.
i apologize for my temporary(hopefully) retardation

Re: Infinity * Zero = Any Number ARGUE HERE

I just noticed this thread and I was leafing through it, learning as I went. I don't know if this issue has been taken care of yet (I didn't feel like reading all the way through the thread), but I just wanted to give my input.

It may be farther down the line, but that's irrelevant, because EVERY stone, no matter how far down, has a stick that can be matched with it. So the two have to be equal.

I think what Shash is saying here is true because if -...-...-...- goes on forever (infinity) then there are infinity # of sticks and infinity # of stones. So you can't really say that there are more sticks than stones, because if the set goes on forever, then there are infinite amounts of both.

Still don't believe me? Still think "OMG NO JOHNNY 3:1 3:1 3:1!!!"? Then look at this:

Let I stand for infinity.

(I have to also remind everyone, just for my own sake, so I don't get a billion questions later, that if you multiply 2 and X, you can write it as 2X. That's what I'm doing here.)

Look at the fact that 1I = I, and then look at the fact that 3I = I. If I've read this thread correctly so far, both of those things are true. Well, if those things are true, we can say that 1I is the same as 3I, right?

So, if 1I is the same as 3I, then it makes sense for Shash to say that there are an equal amount of sticks and stones if the pattern is indeed infinite.

If that hasn't been taken care of yet, I believe it has been now.

Re: Infinity * Zero = Any Number ARGUE HERE

I don't believe you can have 3I and I, infinity is infinity.

Re: Infinity * Zero = Any Number ARGUE HERE

Well, I don't know if anyone in here is in Calculus, but you can have infinity x 0 = any number... it just depends how you arrive at infinity and zero. Also, you have to assume you CAN go out to infinity.

For instance, take the limit of x sin(1/x) as x goes to infinity. The "x" term will approach infinity (obviously), and the "sin(1/x)" term approaches 0. Yet, as we can see on a graphing calculator, the ends of this equation clearly go to 1. So in this case, infinity x 0 = 1.

In another example, take the limit of x ln(x) as x goes to 0. The "x" term reaches 0 and the "ln(x) term reaches -infinity. Using l'Hopital's Rule with (ln(x))/(1/x), the limit is now (1/x)/-(1/x^2). Multiply top and bottom by x^2 and now the answer is the limit of -x as x goes to 0, which is 0. Here, infinity (or rather, -infinity) x 0 = 0.

It all depends how the numbers are reached...

1/inf APPROACHES zero.

Don't hurt yourself yelling. And before completely displaying your stubbornness, first consider this:

Imagine you are running down a road and you are trying to catch up to a turtle. You approach the turtle and get to half the distance to the turtle from where you started. You then get to half that distance. This continues.

When does it stop? Your distance to the turtle, as its being halved an infinite number of times, approaches 0. If it never reaches 0, you can never pass the turtle.

This is one of Zeno's paradoxes. It's also a gigantic headache. The thing is. Since you can actually pass the turtle, something has to happen to your distance as it gets closer to zero. What happens? Leave that to physicists. What we do know is that basically the distance at some point becomes non-existent. And so why can't the distance between two numbers have the same effect?

In other words if X approaches infinitely close to infinity why can't X be infinity?

Besides, X was approaching infinity, not 1/inf approaching 0.

Well, I don't know if anyone in here is in Calculus, but you can have infinity x 0 = any number... it just depends how you arrive at infinity and zero. Also, you have to assume you CAN go out to infinity.

Well, I am in calculus. It's nice to meet someone who knows what they're talking about.

For instance, take the limit of x sin(1/x) as x goes to infinity. The "x" term will approach infinity (obviously), and the "sin(1/x)" term approaches 0. Yet, as we can see on a graphing calculator, the ends of this equation clearly go to 1. So in this case, infinity x 0 = 1.

Sorry to be an ogre (especially if I turn out to be wrong) but....

The limit as x approaches infinity of sin 1/x does not equal 1. The sin of 0 does not equal 1. Sin (0) = 0. The limit as x approaches infinity of cos 1/x does equal 1 however.

In another example, take the limit of x ln(x) as x goes to 0. The "x" term reaches 0 and the "ln(x) term reaches -infinity. Using l'Hopital's Rule with (ln(x))/(1/x), the limit is now (1/x)/-(1/x^2). Multiply top and bottom by x^2 and now the answer is the limit of -x as x goes to 0, which is 0. Here, infinity (or rather, -infinity) x 0 = 0.

It all depends how the numbers are reached...

I actually thought this had a mistake until a minute ago:

{all numbers except inf}

I was sure that zero did not belong in the set for a second. But you've saved the day with your limit. My class actually had to rush through the limit as x approaches infinity and negative infinity section. No worries, I still understood it. We just never got to the limits of natural logarithms.

Actually, with limits you can prove that infinitesimals = 0.

Re: Infinity * Zero = Any Number ARGUE HERE

but still isnt anything * 0 still 0????
its basic mathematics
say infinity = 99999999999999999999999 in this case
99999999999999999999999 * 0 = 0
no matter how you look at it anything * 0 = 0

[xinpig]

Re: Infinity * Zero = Any Number ARGUE HERE

this is just like pi

btw x/inf gets you a very small # provided x does not = 0
it just tiny .00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001
still aint 0 no matter how many 0 you add
