"Webb3 apr. 2012 · I think you are going to have to solve a system of 2 quadratic equations: one is your equation of the ellipse a x 2 + b y 2 = 1, the other is b y ( x − p) − a x ( y − q) = 0 where ( p, q) is the point outside of ellipse. The second equation expresses the orthogonality of the vector x − p, y − q to the ellipse. " - The outer boundary of a circle
