shooting method. please find attachment

Hello admins. Can you please guide me on what's going wrong with my post? I just posted and now my post has been deleted or vanished?

Hello experts,I need your help to obtain the solution of the mentioned equation in the attached picture by using the newton method by supposing the random value of involved constant like D  etc. I need an algorithm for the newton method for the mentioned equation. note h=1+x^2/2
