4.C. In polar coordinates the radius can be negative a. Suppose a point is given (r, 0) = (3, -) where -= 180 + 450 . Plot it below and label it as P b. Come up with the coordinates of P but with a negative radius and 0 is between 0 and - , that is to say, the angle must rotate CCW and be in quadrant I. c. Come up with the coordinates of P but with a negative radius and 0 is between and N -27t, that is to say, the angle must rotate CW and be in quadrant
