A method for computing the perimeter of an ellipse.
Essentially, the problem of calculating the distance from the equator to the pole is to calculate the quadrants and the perimeter of an ellipse.
There is no unique solution to this, so here are several formulas that can be used.
Two solutions with infinite series are the most accurate.
Vectorized.
