There's a section in the documentation called "How do I move the camera
in a circular path?. Section 2.4.1.3 in Pov 3.6. Section 9.1.1.3 in POv
3.5.

In particular, if you look at "the mathematical way" it goes on to
explain how to adapt this method to move the camera in an elliptical
path, which seems to be what you are actually trying to do.
