 Author Comment/Response MOS was 71331 05/16/13 10:29pm (* Finding the closest and farthest points on an ellipsoid to (4,6,13). *) Minimize[{(x - 4)^2 + (y - 6)^2 + (z - 13)^2, x^2 + 2 y^2 + 6 z^2 == 1}, {x, y, z}] Maximize[{(x - 4)^2 + (y - 6)^2 + (z - 13)^2, x^2 + 2 y^2 + 6 z^2 == 1}, {x, y, z}] I get results which seem reasonable: Closest: {205.6944, {x ->0.4746151, y ->0.3784113, z -> 0.2852923}} Farthest: {237.2617, {x ->-0.541713, y -> -0.3804159, z -> -0.2636648}} I want to plot the ellipsoid, but my code doesn't work.
