(1 point) (a) The Cartesian coordinates of a point are (-1, -13). (1) Find polar coordinates (r, 0) of the point, where r > 0 and 0 << 21. r= 2 = 41 3 (ii) Find polar coordinates (r, 0) of the point, where r < 0 and 0 < 0 < 21. r= 2 = ?3 2 (b) The Cartesian coordinates of a point are (-2,3). (1) Find polar coordinates (r, 0) of the point, where r >0 and 0 < a < 21. r= 713 = arctan ctan( - ) (ii) Find polar coordinates (r, 2) of the point, where r < 0 and 0 <0 < 21. r = V13 = arctan (-1 mlar
