Show that the function

where z = x + jy and w = u + jv, maps the circle |z| = 3 on the z plane onto a circle in the w plane. Find the centre and radius of this circle in the w plane and indicate, by means of shading on a sketch, the region in the w plane that corresponds to the interior of the circle |z|= 3 in the z plane.
