4. From a different angle, your umbrella protects you by tracing the polar curve r = m, while the goose attacks you by tracing the polar curve r = cos(mb) +m+1. For both curves, 1 (i) sketch the graph of r as a function in in the Cartesian coordinates, and then (ii) sketch the curve on the xy-plane. How many times does the goose hit your umbrella when Є [0,2π)?
