45pi4 find three additional polar representations of the poi

(4,5pi/4) find three additional polar representations of the point, using -2pi<theta<2pi

(4,5pi/4)

in -2pi to 2pi, only one other representation is possible which is (4,-3pi/4)

other representations -

theta = 2pi + theta = 13pi/4

theta = -2pi + theta = -3pi/4

theta = 4pi + theta = 21pi/4

theta = -4pi + theta = -11pi/4
