Find three additional polar representations of the point(4,3pi) , using −2𝜋 < 𝜃 < 2𝜋. (Enter your answers in order from smallest to largest first by r-value, then by 𝜃-value.)

Answer 1

(4,-pi)

or

(4,pi) or

(4,-180 degrees)

(4,180 degrees)

all equivalent to

(4,3pi)

in rectangular coordinates, the point is (-4, 0)

r=4 as the only r value in polar coordinates, but theta can be 3pi + 2npi where n= any integer

but the only alternatives within the range -2pi < theta < 2pi are theta = + or - pi
