2 Bessel functions are useful in the analysis of problems that involve oscillations Very impor tant equations in differential equations involve Bessel functions in their solutions If a is a positive integer the Bessel function Ja r of the first kind of order a is defined by the power series Ja 3 n a 2 n 0 Show that this power series is convergent for every real number x 2n a
