We deduce some approximate formulas for the distance evaluation problem between a point and an ellipse in IR~2 and a point and an ellipsoid in IR~3. The proposed approach is based on the analytical representation of the distance function as a zero of an appropriate univariate algebraic equation...

Thus the line intersects the sphere when t=-4, corresponding to the point (-7,-2,-7), and when t= 83, corresponding to the point ( (19)3, (14)3, (19)3). The ellipsoid is a level surface of F(x,y,z)=4x^2+y^2+4z^2 and ∇ F(x,y,z)=8x,2y,8z, so ∇ F(...
