Best ResponseYou've already chosen the best response.1Here are two simple examples. 0 is an accumulation point in the reals of this set: A = { 1/n  n nonzero integers } An adherent point of the interval (0,1) is 0, as is 1.

Best ResponseYou've already chosen the best response.1This sort of mathematics doesn't work that way. They are both technical definitions and I have to say I think these two examples are pretty straight forward. You develop your intuition about them not by looking for loose analogies in the "real world", but by looking at these examples and others carefully, and be reading a couple of proofs where these definitions are used.

Best ResponseYou've already chosen the best response.1it's not always obvious where these sorts of technical definitions come from or why they'd be useful. That's why looking at proofs is important. I have to say accumulation points come up quite a bit in elementary analysis. Adherent points is not a concept that's not very useful in my experience.
