For a sequence (an)n=1;2;::: of positive real numbers, limn!1 an = +∞ holds if and only if limn!1(1=an) = 0. Proof. Suppose limn!1 an = +∞.Given" > 0, let M:= 1=".Since limn!1 an = +∞, there exists a positive integer N such that n > N implies an > M = 1=".Consequently, n > N implies 1 an − 0This shows that lim
