1/0 is infinity because 0 goes into 1 an infinite number of times.
Why do mathematicians force this "undefined" autism onto us?

Anonymous No. 16274394

Look at the graph 1/x.
As x approaches 0 from the left and the right, there is a disconnect or discontinuity on the graph.
Left limit != right limit, so it's undefined.

You're an idiot, so your sense is worthless.
This is why counterintuitive problems exist, because you're too dumb to understand them.

>if 6/2 = 3
>then 2 * 3 = 6
now consider the following:
>if 3/0 = infinity
>then 0 * infinity = 3
>if 4/0 = infinity
>then 0 * infinity = 4
you see the problem? That's why we say anything directly divided by 0 is undefined. It APPROACHES infinity sure, but it's still undefined at 0 itself.

How do you know there's discontinuity? Maybe you need to make a really big graph and see that the left and right will finally meet somewhere?? Answer it without saying infinity because then your definition of infinity would be circular.

1/0 = infinity
-1/0 = -infinity
That was easy.

Infinity is logically contradictory (Finitist gang) so "undefined" is the best answer, since it simply acknowledges there isn't really an actual answer at all. Better than pretending 2 has a square root and inventing a make-believe number for it.

But both sides get closer and closer to y axis so they'd at some point touch y axis

because the moment you allow infinity to be a number you realize their system has infinite amounts of contradictions.

then what's 1/0 ? you see there are 2 possible answers and that's not how it works , therefore it's undefined

That's who I got the point from my man, he has a spectacular point that it's not that the square root of 2 is irrational... it's that there isn't one.

If you accept rational numbers, then you should accept irrational numbers.
An irrational number is just an infinitely specific rational number.
For example, if you multiply 1.4 by 1.4, you get sorta almost to 2. If you add a few more decimal places, you get closer still. Repeat, and at the limit you'll get exactly 2

Rational numbers are already infinitely specific.

Ah, but there are no two finite numbers you can divide into each other that can multiply with itself to be 2

Isn' this kinda a contradiction in terms? I think limits are never actually reached

sqrt(2) doesnt exist and isnt a number.

Anonymous No. 16276646

Correct, but 0 goes into 2 "infinite" times too. As well as any other number you want to name. So whatever you want to call the value this quotient, it can't be considered a number

That's not a response. What excludes 1/0 and 2/0 from having the same result? 1*0 and 2*0 are both the same value, can it also not be considered a number?

Limits are never reached physically, but mathematically they're well defined and calculable exactly.

Anonymous No. 16276771

Yeah you can calculate the limit but if you're working with a limit then you're saying that what you're doing doesn't actually ever reach there

Anonymous No. 16276777

I'm saying you can reach irrational numbers from rational numbers at a limit by getting more and more accurate
But it's true, you never go from rational fractions to irrational real numbers

My apologies, I like posting screencaps from Wildberger videos when people start assuming stupid things they think he would agree with, like 0.999... โ‰  1
That said, the proof you mention is really just a philosophy on the nature of the contradiction generated from assuming sqrt(2) is a rational number. I think he's put out some pretty good recent videos explaining why he feels that "converges to a transcendental" is affirming the consequent compared to "converges to a rational number".

Do you think, in the actual world of things that genuinely exist and are causally potent, that there could ever be something that truly was the quantity "square root of two"?

I demand that you show me a physical quantity 1 of anything. The number 1 does not exist until you show me exactly 1 of something that satisfies my definition.
