Correct.

What's your question?
>>11402268
> [math]a>b[/math] is an equivalence relation
It isn't.
>>11402352
>a condition for every [math]n \in \mathbb{N}[/math]
Iff x=1.
>am I expected to come up with a simpler/different solution?
I'm pretty sure you're supposed to literally brute force this problem.
[math]|x^2-1| < 1/n[/math] if and only if [math]x^2 - 1 <1/n[/math] and [math]-x^2+1 < 1/n[/math] , because modulus.
Do some algebraic manipulation, get two conditions.
Or split it up in [math]x>1[/math] and [math]x<1[/math], same same.

Acquire great anger.

Vixra already exists, tho.

It's literally one fucking guy and we play along for jokes.

>is Z even a vector space
OHHHHH, THAT'S WHY THE QUESTION DIDN'T MAKE ANY SENSE.
Fuck, I was also thinking it was algeo.
Lad, try using the definition of a base.

Every group has a natural structure as a Z-module.

There you go.

Not quite. For example, one file could be the part one, and another the part two, etc.

Of course you do, dummy. No Cash-poster can possibly be that stupid.
