comment If a function is uniformly continuous on $(-\infty,-1]$ and $[-1,\infty)$ is it uniformly continuous on $\mathbb{R}$
@Lierre - I don't think it's a typo. It would be silly to leave out ]-1,1[ and conclude that it's uniformly continuous over $\mathbb{R}$. -1 and -1 mentioned 3 times in the question, and that's also how Henning in the accepted answer interpreted it. I therefore rolled back your edit.

@Lierre - the question is about -1 as endpoints of both intervals, not -1 and 1.

I don't agree. Your argument would be valid if the intervals were half-closed, but both are closed, so the union is uniformly continuous.

comment What is the most frequent number of edges of Voronoi cells of a large set of random points?
Not a useful answer if all you get to see is a table of contents.

comment How do I scale 3 fractions to 3 natural numbers?
Second question: now that I see it, it seems obvious. I just couldn't see how to take $a$ and $b$ apart. Thanks.

I saw that, but misinterpreted. Sorry about that.

comment How do I scale 3 fractions to 3 natural numbers?
Ah, the $x$, $y$ and $z$ are not my natural number result then? Because if they were, their $\gcd$ would also be natural.

"and that r is maximal rational number". Is $r$ rational, or natural?

Yes, thanks. +1. It's too early for an accept, there might come other answers.

comment Missing steps in the calculation of limit?
Thanks for the quick reply. But my problem is that in the application frequency is zero, I apply the limit for that case, as I mention in my question.
