Abstract

In this paper we shall discuss the moment integrals of 1/sint as a generalization of one of the integral representations of the Catalan constant. As an application of our formulas, we shall derive several relations among the Riemann zeta-, the Dirichlet L-, and multiple L-values mod 4.

Notes

  1. We note that various properties of the integral \(\int_{0}^{x} \tan^{-1}(t)/t \,dt\) was studied by Ramanujan [14]. See also Berndt [6, p. 265, Entry 17].
