(b) Show that the series is a solution of the differential equation \(x^{2} J_{1}^{\prime \prime}+x J_{1}^{\prime}+\left(x^{2}-1\right) J_{1}=0 .\) (c) Use a graphing utility to graph the polynomial composed of the first four terms of \(J_{1}\). (d) Show that \(J_{0}^{\prime}(x)=-J_{1}(x)\).
True or False? Determine whether the statement is true or false. If it is false, explain why or give an example that shows it is false. If \(n>1\), then \(n !=n(n-1) !\).
Use a graphing utility to graph the function. Identify the horizontal asymptote of the graph and determine its relationship to the sum of the series. $$ f(x)=2\left[\frac{1-(0.8)^{x}}{1-0.8}\right] \quad \sum_{n=0}^{\infty} 2\left(\frac{4}{5}\right)^{n} $$
