97 (9.+2) 9. 4 9. 97 4 Step 2 We now must find a pair of polar coordinates that represents the same point with a radius r < 0. Recall that for a negative radius, the resulting point is on the same line through the origin as the point with positive radius, it is the same distance from the origin, but it is on opposite sides of the origin. 5 (9, 4 (9, The angle of the direction opposite the point (9, 1) is a = C
