Orbit precession

  1. Sep 9, 2014 #1
    the problem says:

    "consider a particle with orbit

    ##r(\phi)=\frac{r_0}{1-\epsilon \cos (\beta \phi)}##

    ##\epsilon \in ]0,1[## and ##\beta=cte##

    a) Find the precession angle.

    b) What is the condition to the trayectory is totally cyclic??
    __________________

    I dont understand why i calculare the precession angle. If I draw ##r(\phi)## i view that the grraphics precesse for ##\beta \in ]1,2[##, but i need calculate the angle.

    the answer of b) is ##\beta=integer##????

    c being the speed of light, e= 2.71828182846, t being time?
