Thema verfehlt. The question is: How does NUF(x) increase from 0 to more? You know? There is a point where NUF is 0 and then it increases. How?Can you explain how NUF(x) can [jump] from 0 [at x = 0] to [aleph_0] [at any] point x [> 0] although all unit fractions are separated by finite distances [...]Yes, of course: For each and every x e IR, x > 0 there are countably-infinitely many unit fractions which are <= x. (Hint: No first one.)
Not that hard, is it?
