9 5x is a The angle of the direction opposite the point 9 is 5x OF Step 3 We have found that the angle of the direction opposite the point 9 7 is a ST 4 Submit Skip you cannot come back r 8 Therefore a pair of polar coordinates that represent the same point as Therefore the point opposite 9 5 9 n s but with r 0 is should be our original point This is in fact an example of the general fact that r 6 represents the same point as
