Question

Name 3 different representations of the following (-6, 3pi/4)

Answer 1

I will assume that (-6, 3π/4) is in polar coordinate form of the type (r,Ø)

so just add multiples of 2π to your rotation, and you will end up at the same point

or

reverse the direction and change the angle to the clockwise rotation

e.g. ( going counter-clockwise 135° is the same as going 225° clockwise)

(-6,3π/4) ----> (6, -5π/4

so 3 different versions could be
(6,-5π/4)
(-6, 11π/4)
(-6, 19π/4)
