I am stuck on the last problem of my complex variable homework.
The problem is given the set $S=\{\frac{i}{n} \mid n \text{ is an integer}\}$,
a.) List the points in $S$.
b.) What are the accumulation points of $S$?
So far I have the points being $i$, $i/2$, $i/3,\ldots , i/n$ but that seems like it is too easy for this class.
Am I missing something?
The second part, I would think there are not any accumulation points because none of the neighborhoods of the points will include any other points for a small neighborhood.
Any help would be appreciated.
