Numerically

I had to compute the length of arcs of Earth's meridian. I noticed that there was no analytical solution for this so I wrote this very simple function.It computes the arc length of an ellipse centered on (0,0) with radius a (along OX) and radius b (along OY)x(t) = a.cos(t)y(t) = b.sin(t)with...
