3. (15 points) r = sin(20) r = cos(20) a) Sketch both polar curves on the same graph. b) How far should we let 0 run to traverse the curves one time only? OC eonly? OLO c) Label the points of intersection IN THE FIRST QUADRANT ONLY, on the polar graph, of the two curves using the angles. If the point has different angles for cosine and sine, indicate this. Note: Rest o
