no, 0.999 = 1
(1+2+3...) = 2
if it was (-3 + -2 + -1 + 0 + 1 + 2 + 3) it would be true but the negative numbers are -1 so -1 + 2 = 1

I will prove the second identity. The first follows trivially

Proof:
-24 * (1 + 2 + 3 + ...) =
-24 * (-1/12) =
24/12 =
2 =
1.999...

What? It clearly doesnot diverge you moron.

Do you want me to step by step compute the sum to show it...

wait...

Oohh. HAHAHAH. You fucking retard think that we are definiting the convergence of an infinite series by the limit of partial sums? Top kek. Are you an undergrad calc 2 babby? Are alternate theories too hard for babby over here? How is calc 2 going huh? Did you already memorize the integral test for convergence? I hope you did! It is a pretty important theorem!

Hahah... Good talk with you kid. But call me when you are at least in your third course in real analysis.

I put it there. I am trying to prove that 1.999... = -24(1+2+3...)

And I did it by taking the right side and manipulating it into the left side.

God damn man. I am clearly shitposting but the way you are perceiving my shitpost is so far off what the meaning of my shitpost is.

You think my shitposting has to do with me being wrong but I am actually right in a very shitposty manner. This is basically shiposting math. 1+2+3+... = -1/12 is shitpost math.

Stop being such a stuck up cunt. It is clearly divergent. Only because you can use certain methods to assign a finite numbers to divergent series to give them a meaning in physics still doesn't make them convergent.

top kek you really are an undergrad babby. Go back to practicing the product rule. That's a real tricky one!

False, the series on the right diverges so it's not equal to the finite value on the left.

I'm not even the same guy you replied to in the first place, he abandoned thread, rightfully so. But you are saying it yourself, it is a summation issue. It STILL doesn't make a divergent series magically convergent, stop falling for memes.
