3. If Z and W are two distínct points on the Riemann sphere, then the plane through these points and the origin cuts the sphere in a "great circle," that is, a circle with maximum diameter (2, for a unit sphere). Show that this great circle corresponds to the unique circle (or line) in the plane that passes through the points z, w, and 1/z, where Z, W are the projections of z, w respectively. [HINT: See Prob. 2.]
