I thought the gradient of y was undefined, not infinity.

y*x = -1

y*0 = -1

y = -1/0

Therefore y is undefined.

Might be completely wrong here though.

 

[ilikebeeef]

infinity isn't a number. Logically, infinity * 0 is 0 but you can never finish multiplying it so it's undefined.

+1.

 

[meilz92]

Is infinity x 0 = -1?

no its 69 hurrr derrrr

 

[shaon0]

x-y axis are perpendicular because its easier to find distances between points. And, 0.9 (recurring)=1

You are right. The gradient of the y axis in undefined.

But you can also says its infinity, in a way.

Jesus.

People really ate this thread up, didn't they?

It approaches it but never reaches it.

 

[hscishard]

It approaches it but never reaches it.

I know. But when trying to put into a fraction...how gay lol

That method thing implies infinity is a constant.

 

[hscishard]

That method thing implies infinity is a constant.

It does? Cool. Now maths is pretty stuffed.

 

[kaz1]

Anything multiplied by infinity is infinity and anything multiplied by 0 is 0. So it's pretty much a paradox imo.

 

[kaz1]

It approaches it but never reaches it.

It does and you can prove it but i cbf right now.

 

[twistedrebel]

mate you should do chaos maths, (Phd level) then spend 3-5 years trying to prove that.

 

[brunx]

is this a legit proof?...

0.999.... let equal x
10x = 9.999...
10x - x = 9x = 9.999... - 0.999... = 9
ie. 9x=9
x=1
0.999... = 1

 

[hscishard]

Dunno. But the concept is correct for other recurring decimals. In a way for 0.9 repeata = 1 it kinda contradicts itself.

0.999.... let equal x
10x = 9.999...
10x - x = 9x = 9.999... - 0.999... = 9
ie. 9x=9
x=1
0.999... = 1

This is the proof.

 

[brunx]

This is the proof.

is it flawed? or do expert mathematicians reckon this definitely proves 0.999... = 1

 

[untouchablecuz]

OMG. I know where you guys are comming from. I know the facts.
But I found it interesting. Jeez.

Fine heres a question. Prove that the x axis is perpendicular to the y axis.


(No, i'm not saying infinity x 0 is -1!!!)

they are defined to be perpendicular. the x axis and the y axis arent magical lines that are by nature perpendicular

 

[shaon0]

It approaches it but never reaches it.

No, 0.9 (recurring)=1. Not approaches.

 

[ohexploitable]

I don't like maths anymore
