Abstract:
Discussed the decision problem on the convergence and divergence of a class of seriesn∑n=1∞[((2n-1)!!)/((2n)!!)]^p(p∈R) and its derivatives by establishing a group of discrete inequalities {1/(2n^(1/2))}^p≤[((2n-1)!!)/((2n)!!)]^p≤{1/(2n^(1/2))}^p(p0) and {1/(2n^(1/2))}^p≥[((2n-1)!!)/((2n)!!)]^p≥{1/(2n^(1/2))}^p(p0).Gave some corresponding application.
Keywords:series  inequality  convergence and divergence
