Need help on some problems w/ accumulation points

  1. Sep 28, 2008 #1
    1. The problem statement, all variables and given/known data
    Give an example of a set with exactly two accumulation points.



    2. Relevant equations
    We can use the defintion of accumulation points

    3. The attempt at a solution

    I really have no idea where to get started on this. If I could get a hint that would be great thank you

    Well, you listed the "definition of accumulation points" as a "relevant equation"! What is that definition.

    Suppose you had a sequence such as {1, 1/2, 1/3, ..., 1/n, ...}. That is a set of real numbers. What are its accumulation points?
