Webspherical problems the order is of half integer value (ν = n +1/2). Since Bessel’s differential equation is a second-order equation, there must be two linearly independent solutions. Typically the general solution is given as: y = AJ ν(x)+BY ν(x) where the special functions J ν(x) and Y ν(x) are: 1. Bessel functions of the first kind, J
