Oh... I don't know why... but you can see the equations in the attachments below... thanks
 


how can solve bessel equation by runge-kutta, beginning with positive value of x and y ,and y' (integrat forward and backwar in x )plot y with c language
please help
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
