i have been able to solve second order ordinary differential equations but with initial conditions for the function and its first derivative. i need to solve the same differential equation with boundary conditions.

Thanks in advance,

Rogelio

In your document many indefinite variables (if you want to use procedure "Given-Find" for the numerical solution of the equations).

For solution of the system of odes you can use the function sbval for the finding the initial conditions (a Coushy task) and than use functions rkfixed, rkadapt odesolve etc
