These pages present the mathematics which was used to create the images on the previous page.
The aim was to illustrate the so-called advance of perihelion of mercury's orbit as predicted by Einstein's general theory of relativity, and to show a calculation for the Newtonian orbit using a curved Riemannian 3-space. The former aim is the reason Mercury was chosen, and the former aim is also the reason that the plural of sun appears in the title: The advance of perihelion will be greatly enhanced if the sun is replaced by a star which is 1,000,000 times more massive. To further exaggerate the effect, the parameters were changed to make the Newtonian orbit more eccentric, but without changing the perihelion.
