*The solutions of this equation are called Bessel Functions of order n.  

*Bessel functions of the first kind, denoted as <math>Jn(x)</math>

*Bessel functions of the first kind, denoted as <math>Jn(x)</math>

*The Bessel function of the first kind of order can be expressed as: <math>Jn(x)=\sum_{k=0}^\infity){(-1)^k(x/2)^n+2k}/k!gamma(n+k+1), where gamma(n+k+1)=(n+k)! or                                                                      *Integral 0 to infinity  x^(n+k).e^-x dx. is the gamma function.
