TL;DR: In this article, the exact forms for the reactive energies and modal quality factors in the literature are given for two polynomials having positive coefficients which are readily calculable.
Abstract: Compact expressions are given for the reactive energies and modal quality factors in the literature. The formulas do not involve spherical Bessel functions and are in terms of, at most, two polynomials having positive coefficients which are readily calculable. Curves are presented for the exact forms for a number of modal quality factors.

TL;DR: In this article, the author has estimated the orders of the coefficients of Bessel series of a function which is differentiable 2S (S≥ 1) times and derived the uniformity of the convergence of the Bessel Series in the interval (a, b).
