1.Does a sequence exist that has every point of R(real numbers) as an accumulation point?
2.Show that closed is essential in the Heine-Borel Theorem by finding an open cover of a non-closed bounded set that does not have a finite sub-cover.
I think that the set of rational numbers has every real numbers as an accumulation point, but I'm unsure of the sequence of rational numbers.
Any help appreciated, thanks.
