Question

Determine two pairs of polar coordinates for the point (2, -2) with 0° ≤ θ < 360°.


the answer choices are;
(2√2, 225degree), -2√2, 45deg)
(2√2, 135degree), -2√2, 315deg)
(2√2, 315degree), -2√2, 135deg)
(2√2, 45degree), -2√2, 225deg)

Answer 1

the second one, and the fourth one because the vector 2, -2 goes toward the fourth quadrant and the opposite(315-180) is 135 so that is the second one

Answer 2

so its (2√2, 135degree), -2√2, 315deg)?
