This is given by Eq. (7) in the approximation of Eq. (5), and by Eq. (10) in the next approximation, the equation following equation (8). These equations can be used to describe any precessing orbit with precision and the ECE2 equation is clearly preferred to the Einstein equation because the latter has been refuted in nearly a hundred different ways in the UFT series and refuted in many other ways by many authors for many years. It is used only by dogmatic ostriches who hope that ECE2 will go away, but it’s here to stay.
