if n is odd. Hence, (−1) nn n+1 is within of either 1 or −1. Since the distance from a to both 1 and −1 is at least 2 , we see that for all n ≥ N the distance from a to (−1) nn n+1 is at least . Therefore, at most finitely many elements of B can be within of a, so a cannot be a limit point of B. Hence, no number a such that |a| 6 = 1 can be a limit point of… CONTINUE READING
