Derivation and Evaluations of a Generalized Finite Integral Involving Transcendental and Hypergeometric Kernels

Abstract

In this paper we have established a finite integral involving the product of the hypergeometric, exponential, and rational functions in terms of an infinite series. The infinite series involves the product of the incomplete gamma function and a rational function which can be reduced to the Hurwitz-Lerch zeta function as a special case. Other results are possible for various special cases of the parameters involved. The finite integral will be used to derive formulae involving elliptic functions, product of logarithm functions and a few other special case examples which are new to best of our knowledge along with errata for examples in some well known textbooks. The method used to derive this integral is contour integration. The parameters involved are valid over the complex plane unless stated otherwise.
