Question
Describe the region on the unit sphere that is covered by the image of the Gauss map of the
following surfaces (make sure to specify your choice of the unit normal vector field). You don't
need to include any proof/computations for this problem. Instead, draw pictures and visualize the
surfaces.
(a) A plane defined by x + y + z = 1.

(b) An ellipsoid + G + 4 = 1, a, b, c > 0.
6²
(c) A paraboloid of revolution z = x² + y².
(d) A helicoid parametrized by
X(u, v) = (v cos u, v sin u, u),
u, vER.
