1 Introduction. - MIT
web.mit.eduThis is a boundary value problem for the function f( ) which has no closed form solution, so we need to solve it numerically. Solving boundary value problems numerically is not an easy task. We would like to reduce this boundary value problem to an initial value problem. For the equation (3.48) this is possible. If F( ) is any solution of equation
