For each of the following shapes, draw their projections onto each of the xy-, xz-, and yzplanes, and specify which of these projections are one-to-one.
(a) The portion of the cone x^2 + y^2 = z^2 satisfying 0 ≤ z ≤ 1.
(b) The portion of the sphere x^2 + y^2 + z^2 = 1 in the first octant: where x, y, z are all nonnegative.
(c) The portion of the surface z = sin y satisfying −1 ≤ x ≤ 1 and −π ≤ y ≤ π.
