Find three additional polar representation of the point (-3, pie over 6) given in polar coordinates,using -2 pie <0 <2pie.
All you have to do is find coterminal angles or else
change the -3 to +3 and state the angle which goes in the opposing direction
eg. (-3,π/6) or (3, 7π/6)
to get coterminal angles just add 2π to your angle
e.g (-3,π/6) and (-3, 13π/6) puts you in the same spot
