Parametric equations of an ellipse: x = a cos θ, y = b sin θ
Radius of curvature R = \frac{((dx/dθ)^2 + (dy/dθ)^2)^{3/2}}{|dx/dθ d^2y/dθ^2 - dy/dθ d^2x/dθ^2|}
Center of curvature coordinates: x_c = x - \frac{(b^2/a) cos^3 θ}{(a^2 sin^2 θ + b^2 cos^2 θ)^{1/2}}, y_c = y - \frac{(a^2/b) sin^3 θ}{(a^2 sin^2 θ + b^2 cos^2 θ)^{1/2}}
