[SOLVED] Complex limit points

This is the first of a probably numerous series (pun intended) of questions about complex series. My series work has never been good, and I don't write proofs well. (Headbang)

So here we go with the first:

Quote:

A point

is said to be a limit point of a set E of points in the complex plane (as opposed to a sequence

) if every neighborhood of

contains infinitely many (distinct) points of E. Show that a sequence

can have a limit point

in the sense that, given any

the inequality

holds for infinitely many points of

, without being a limit point of the set of points corresponding to the terms of

.

I can't even think of an example that fits this situation, much less writing a proof for it. Any pointers (not full solutions please) would be appreciated.
