@Lemon Yes, you are absolutely on the right track. See also my update.

comment How to check if a function is significant or not?
@user3193259 Yes it is going to zero. However, it is decreasing very slowly. On your graph it will seem like it is never going towards zero, because for $f(n)$ to be less than, say $1 / 10$, you would need to set $n > 10^{100}$ (with log = base 10)!

@user3193259 The base doesn't matter, it is still going to 0 in the limit (see e.g. here)

comment How to check if a function is significant or not?
@user3193259 You have $f(n) = \frac{1}{\sqrt{\log n}}$ right? This function goes to 0 as $n \rightarrow \infty$. Of course it will never be exactly 0, that is why we are calling it a limit. I know that you were asking about whether it was negligible or not, I just wanted to clarify which function you meant, since you said that it did not tend to 0, which got me confused.

As far as I can tell $f(n)$ do tend towards 0 for $n \rightarrow \infty$. Did you perhaps mean a different function?
