I want to solve system of nonlinear ODEs using RKF with shooting technique. If some body have a idea please help me coding I am new In Maple. If somebody have a relevant code please share with me. I try to understand and then apply on my problem. 

I want to solve attached link paper and image.Thanks

I want to solve system of nonlinear ordinary differential equations numerically using the variational finite
element method (FEM). is it possible to solve on Maple? If anybody have a idea please share with me. I attach the image of my problem which I am tryimng to solve.
