Question

PLEASE Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°.

I've narrowed it down to the following choices:
A.
52√,−(π4)

B.
52√,−(π4)+2pi

C.
−52√,−(π4)+pi

D.
−52√,−(π4)−pi

But my answer choices are these:
(5 square root of 2, 315°), (-5 square root of 2, 135°)
(5 square root of 2, 45°), (-5 square root of 2, 225°)
(5 square root of 2, 135°), (-5 square root of 2, 315°)
(5 square root of 2, 225°), (-5 square root of 2, 45°)

Answer 1

Run through the steps you took to find your answers...

Answer 2

Would you have any idea which answer would be the closest estimate to the ones i came up with? I dont have the work with me..

Answer 3

Well you see, that's the point. Your answers don't come close enough to be estimates. Give me one second to figure out the problem for you...

Answer 4

Hmm, a bit rusty, but I would say B is your answer...
