this is a meme right. this can’t possibly be correct

Note that

[math] \log(\frac{1}{1-X}) = \sum_n X^n/n [math]

so the statement amounts to saying that the log has no finite limit.
The log grows slowly, but indeed it grows forever, so it diverges.

Besides, the sum even diverges if you just add up the reciprocals of the primes

1/2 + 1/3 + 1/5 + 1/7 + ...

a^2+b^2=c^2
(1)^2+(i)^2=c^2
1+(-1)=c^2
0=c^2
c=0

correct but that's not how the complex phasor plane operates

If you know integration, this is like a discrete approximation of the integral that defines the log function. (the other anon got the log behavior a slightly different way)

[math]\sum_{k=1}^n \frac{1}{k} \approx \int_1^n \frac{dx}{x}=\log n[/math]

The difference between the two sides in the approximation is the Euler gamma constant (in the limit n goes to infinity)

I agree it's pretty hard to conceive how slowly a log function increases, or on the flip side how fast an exponential increases

so what is the slowest growing divergent series?

[Anonymous No.11134956]

>>11134950
I'm not sure if there is such a thing

Suppose there's a slowest growing divergent series
[eqn]\sum_{n=0}^{\infty}a_n[/eqn], then
[eqn]\sum_{n=0}^{\infty}\frac{a_n}{2}[/eqn] grows slower and also diverges, therefore there is no slowest growing divergent series, since we can always find a slower one. However, we can find some really fucking slow ones, take [eqn]\sum_{p \ \text{prime}} \frac{1}{p}[/eqn] this series grows like [math]\ln\ln n[/math] if i recall correctly

By the integral test it diverges

lim x-->inf log(x)=inf

>this series grows like lnlnnlnlnn if i recall correctly
how do i calculate the growth of a given series

Sentences go on virtually forever because reality itself cannot intervene if it was personal against power or happened in proximity. I cannot stress deaths happen literally forever. Over and over again.

If you can find a closed form for the partial sum, you're done, it grows like that. If you can do an integral test sometimes you can compare it to that. That's where we get the log growth for the harmonic series, there are other ways to prove it too. Here's a couple ways to prove the log log growth of the reciprocal prime series:

Other ways include taylor series, fourier series, numerical estimates, etc, it's not an easy question. I'm no expert.
