Not knowing what extended real number line is. Being a dipshit who doesn't know Calculus.

no, both are undefined, x/0 as well as infinity*0

>>951906

Whats wrong with that? In our high school calculus class we r using them as numbers for our limits and stuff.

taking the limit of a number divided by zero =! dividing by zero

Calculus more faggot.

It's an indeterminate form.

There is no quotient!

0=0

2x0 = 63x0

Cancel out the common

2=63

if its literally infinity and zero then zero
if its a function that approaches infinity and one that approaches zero then you'd have to do some simple calculus to figure out where its going.

I see the majority of people here never heard about extended number line. Learn Calculus, retards.

OP, that is an indeterminate form.

>implying infinities don't differ from one another

>>951919
It's funny, cuz you're the one who should learn Calculus.

shudnt it be anything?

>>951945
I will never be a master of calculus who tells people off properly.

>>951964
I'm sad 'day :(

>implying extended real line includes definitions for operations like <span class="math">\infty \times 0[/spoiler]

Also people should understand that division is really nothing more than multiplication by the inverse.
0 doesn't have a multiplicative inverse, and it's pretty much useless to try and invent one.

so, what you're saying is that '0 = anything'?

>>952005
He said that <span class="math">\infty \times 0[/spoiler] is an INDETERMINATE FORM. Before learning Calculus, I think you should learn some basic reading comprehension.

>>952033
Then, bringing up the extended real line is relevant because... what ?

Anything multiplied by 0 is 0, zero trumps all.

God you guys are getting trolled so hard.

>>951918
sure is trololo in here

Anything / 0 doesn't = inf
/thread

thats an indetermination. You could calculate the nearest limit of the function but you couldnt calculate infinite * cero. infinite is not a number. ITS A FUCKING IDEA!

For any x in C
x / y → ±∞
When y → 0
