Unformatted text preview: xzplane, y = c (again with  c  < 1) is a scaled version of the same ellipse, but in the xzplane x 2 4 + z 2 = 1 c 2 and again no points with  y  > 1. inally, the intersection with a plane parallel to the yzplane, x = c , is nonempty provided v v x 2 v v < 1 or  x  < 2, and in that case is a circle centered at the origin in the yzplane of radius r = r 1 c 2 4 y 2 + z 2 = 1 c 2 4 . This surface is like a sphere, but elongated in the direction of the xaxis by a factor of 2 (see igure 3.8 ); it is called an ellipsoid ....
