[amit28it]

While learning about limit points the use of an open ball has been of high discussion. Why can you not use a closed ball to define a limit point?

If someone could give me some intuition as to why I think I may get it.

Thanks.

Amit,

Though not sure of what you were asking for, the curious ME googled the web and found a thread which had the same question(word for word). The discussion in the forum made '0' sense to me, but made me laugh, real loud(you will know if you read).
