Let C be the intersection of a plane ax + by+cz+d=0 with the unit sphere S². Show that x + ży is the image of a point on C under the stereographic projection p if and only if (x, y) is a point on the curve C" defined by the equation 2x 2y ª (2² +²²2 +1) +6 (2² +²3² +1) + ( 2² + ² + 1). a b b the curve C' is the Euclidean circle with center c+d a c+d' + d = 0. Then show that if C does not pass through the north pole N(0, 0, 1), then and radius a² +6² +c²d² (c + d)²
