RegisterBessel function, Neumann functionSolving wave equation in cylindrical and spherical coordinates by the method of variables separation, Bessel differential equation is obtained for a single variable (radial coordinate) If n is not an integer number, linear combination of Bessel functions of order n and -n is the solution of the equation If n = n is an integer number, solutions Jν(x) and J-ν(x) are linearly dependent and Neumann function Nn(x) has to be used as the second particular integral.
