So we just recently did accumulation points in my maths class for chemists. I understood everything that was taught but ever since I was trying to find a reasonable explanation if the sequence an = (-1)n has 2 accumulation points (-1,1) or if it doesn't have any at all. I mean it's clear that its divergent (?), but that doesn't solve the problem. Because the Set of values for the sequence would be just {1,-1}, no values in between. So the general definition of accumulation points doesn't quite fit, or does it? Can somebody explain it maybe in words and in a mathematical way? Thx
