Recurrence Relations for the Maclaurin Coefficients of Products of Elementary Functions and the Bessel Functions

Abstract

In this paper, we investigate recurrence relations for the Maclaurin coefficients of the products of a elementary function and the Bessel function of the first kind $\mathcal{J}(z)=h(z)J_{\nu }(z)$ and the modified Bessel function of the first kind $\mathcal{I}(z)=h(z)I_{\nu }(z)$ in the complex plane corresponding to several specific choices of $h(z)$. In particular, we specialize $h(z)$ as $e^{pz}$, $(1-\theta z{)}^p$, $e^{-p\arctan z}$, $\sin (pz)$, $\cos (pz)$, $\sinh (pz)$, $\cosh (pz)$, $\arcsin (pz)$ and $\arccos (pz)$.
