Re: Sorry, I am born to a Pakistani but cannot read Urdu
Question: what do u call a person who knows only 1 language.
Answer: an American
Re: Sorry, I am born to a Pakistani but cannot read Urdu
Good try.
But:
Watch this video, especially after 2:30. Its not like anything divided by zero is NOT infinity in literal sense, but since infinity itself is undefinable, mathematicians started using the concept of undefinable.
Infinity itself is undefinable by any number or value. Saying other way, if one can define infinity by a number or value, then it is not infinite. 
Re: Sorry, I am born to a Pakistani but cannot read Urdu
No braather, division of real numbers by zero is undefined, not infinity. And infinity can and is defined gracefully as limits, both positive and negative. e.g. lim(+1/x) with x approaching 0 is positive infinity and similarly lim(-1/x) with x approaching 0 is negative infinity. Don’t make the classical school boy error of confusing the two. I don’t have to look it up on the internet.
Now just to recap, division of real numbers by zero is undefined. Undefined is exactly what it means, not defined. Undefined and infinity are two different things altogether. Unlike undefined, infinity can be defined.

dont do it, pryvate. he’s got you approaching his event horizon even before you realize it.
Re: Sorry, I am born to a Pakistani but cannot read Urdu
And here I was, laughing at others who fell for it.
Re: Sorry, I am born to a Pakistani but cannot read Urdu
Fine.
You mentioned +1/x and -1/x with x approaching 0.
I have problem with saying x **approaching **-> 0. (Minus or positive). Why you did not say zero?
I thought we were discussing zero. Not something approaching minus or plus zero. 
Zero is still definable and is an absolute, definable number. But, infinite cannot be defined and measured as far as I understand. And that it has no boundary or limit. One can approach towards it but cannot achieve it.
Please explain the red part in your post a bit further.
P.S. We have drifted far from the topic of thread but still good discussion.

Re: Sorry, I am born to a Pakistani but cannot read Urdu
Rather the joke should be like this
What do yu call a person who knows many languages
multilingual
What do you call a person who knows only 1 language
american
Re: Sorry, I am born to a Pakistani but cannot read Urdu
or arab.
or japanese.
or any of the cultures that weren’t enslaved. 
Re: Sorry, I am born to a Pakistani but cannot read Urdu
Arabs weren’t enslaved? Or maybe there were only colonised.

See, that’s the whole point, Infinity can be defined. The concept is hard to wrap your head around, but take Pi for instance, like any other irrational number (again a subset of real numbers) you can never completely define Pi, so you can never define a perfect circle either. I did mention zero, any real number divided by zero is undefined, yes it has it’s own special form.
Functions on the other hand can result in real values when divided by zero. Take the sinc function for example, sinc(x) = sin(x)/x. It has a peak at x = 0, yes sinc(0) = sin(0)/0 = 1, but 0/0 is still undefined.
How? Enter Calculus drumroll
lim(x->0) sin(x)/x = ?
Using L’Hopital paijan’s handy little rule, we replace the numerator and the denominator with their respective first order derivatives. Now,
lim(x->0) sin(x)/x = lim(x->0) cos(x)/1 = 1
It’s beatuiful, isn’t it? If it still confuses you, you can do a bit of reading on Calculus, or number theory even, if you’re brave enough. There are centuries old problems to be solved, all with a million dollar prize, instant fame, the coveted Fields medal. You can just do what you do here, tell them you are right, stick to it, well you know the drill, make us all proud
Edit: Oh I forgot to explain the part highlighted in red, x approaching 0 is exactly what the guy in the video you linked was doing, the denominator getting smaller and smaller until it reaches zero. Undefined is undefined, if you ever need to define infinity on the other hand just write lim(x->0) 1/x.

Re: Sorry, I am born to a Pakistani but cannot read Urdu
It is still a relevant discussion. Pehle hum Urdu language ki baat kar rahe hain, now we’re talking math language. Still on topic! :k:

This thread is legendary.
Re: Sorry, I am born to a Pakistani but cannot read Urdu
Disputable comment. 
Re: Sorry, I am born to a Pakistani but cannot read Urdu
Sorry for delay in response. Been happily busy. 
Let me ask you a simple question PP! (If you do not mind me addressing you PP to avoid writing your full nick) If you do then let me know.
**Would you believe a street beggar saying and even writing on a piece of paper that this beggar will give you a million currency?
**P.S. I am going to make few more comments soon when I get to them, sorry Mods,… if they are too many in a row.
This is what happens when I cannot get to post soon enough. I may merge them or you can as you feel like it. Too many thoughts at the same time. 
Re: Sorry, I am born to a Pakistani but cannot read Urdu
OK, before PP my friend, could come back or comment, I sincerely expect, PP will not ‘believe’ a street beggar to give him million currency, unless either that person is NOT a beggar by PP’s definition, or PP just is a gullible and too much and unrealistically trustworthy person.
**Pryvate Pigeon bhai, **you reminded me of this occasion:
Not very many people around me know this (just like a lot of them do not know I sometimes sing) and I am sharing this with you and all other readers.
" One day I was studying in a library, a great library which I love and respect and feel honorable to be there many times in my lifetime.
Just before lunch time, there was this guy who sat across me and started talking about mathematics.
He talked great about mathematics and all its subsidiaries.
Along the way, he mentioned that there is such a genius person as his friend, who got 101 out of 100 marks on recent test by his math teacher since he used a very different way to solve the problem and still got the same answer.
I listened to this very passionate and sincere person and said
" That’s very nice. But 101 out of 100 is not possible."
He got irritated. And said " I know but what I meant was that he was so good that even the math teacher had to give him EXTRA marks."
I said: " I see your point my friend, but a math teacher should know there are rules in mathematics to be followed. Giving someone 101 out of 100 does not make any sense."
Well, that did not go very well, he said he was getting hungry and I said I were too.
So we went to the basement kitchen and enjoyed lunch. He decided to sit on separate table.
Few minutes later an older gentleman came to my table and said, he heard every bit of that conversation and agreed with my position. He said:
Mathematics has some rules and regulations and a math teacher should not break those rules.
I said: Agreed and smiled. :)"
More to come. Stay tuned.
