You would find the Center by averaging your data points (assuming you are talking about statistics), I am uncertain about the spread.

All points in a circle are equidistant (not sure if you were implying that or not) and my best guess would be that you would just call it the perimeter.

So for this we can use trig identities.
The one I will be using is:
1 = sin^2(x) + cos^2(x)
because of this we can simplify this equation to:
(cos^2(x))/(cot^2(x)) =
from there we can break up cotangent into:
cot^2(x) = (cos^2(x))/(sin^2(x))
allowing us to have the equation simplify to:
(cos^2(x))/[(cos^2(x))/(sin^2(x))] ---> which you should be able to do yourself
