This is given by Eqs. (4) and (5), which can be solved by computer algebra to give the relativistic orbital differential function (dr/dphi) squared. In the non relativistic limit it reduces to Eq. (8). The all important advance made by computational solution of the relevant Euler Lagrange equations is that this differential orbital function is known now to be that of a precessing ellipse. So this ties up the solution and I will proceed to writing up Sections 1 and 2 of UFT373.
