No.10 (10 points) Let P(6, 31) be a point given in polar coordinates. Find three more different polar coordinates representations of this point where – 27 <0 < 27. (recall that you can also allow r < 0).

## Answer

Vo)) 05:30 350 > x= 66a8(37) = – 4 y = 6sis (37) – J. 4 Consider x = 6 cos (-5) = – – – – y = 6tos sin – 55) = + 12 So P (6, 37 (6,- 59 ) Consider. -6x lost- y = -6x six (-1) = 6 Consider x = -1 y = 4 So required points (6 – 5) (-6, -7) (-6, 78 ) – 6 4. ر ( (-6, 7). 4 are TIL o
