Starting from the generating function [ g(x,t)=\exp!\left[\frac{x}{2}\left(t-\frac{1}{t}\right)\right]=\sum_{n=-\infty}^{\infty}J_n(x)t^n . ] Differentiate both sides with respect to (t): [ \frac{\partial g}{\partial t} =\frac{x}{2}\left(1+\frac{1}{t^2}\right)\exp!\left[\frac{x}{2}\left(t-\frac{1}{t}\right)\right]. ] Using the series form, [ \frac{\partial g}{\partial t} =\sum_{n=-\infty}^{\infty} n J_n(x)t^{,n-1}. ___ _________ ____ __________ ______ _________ ___ _________ _________.
