1. The problem statement, all variables and given/known data

For an elliptic movement, calculate the mean value for a period of $\left( \frac{a}{r} \right)^k$, with $k = 1,2,3,4,5$ and being $a$ the major radius. i.e. calculate

$$\frac{1}{2 \pi} \int_0^{2 \pi} \left( \frac{a}{r} \right)^k dl,$$

being $l$ the mean anomaly.

2. The attempt at a solution

I am a mathematics student, so I don't really know much about physics, I'm a little bit lost in this subject. I've been searching about mean anomaly and I have a slight idea of what is it but I'm really stuck with the problem, if anyone could guide me on the solution I would be really gratefull.
