Question

A. (0,0 degrees)
B. (0,180 degrees)
C. (4,180 degrees)
D. None of the above

Answer 1

C.

Answer 2

@klimenkov Please don't give out answers without explaining. He would not be able to solve future questions like this without an explanation.

To convert a Cartesian coordinate pair to a polar one (in the format \((r, \theta)\)), use this set of formula:

r = \(\sqrt{x^2 + y^2}\)
\(\theta = tan^{-1} (y/x)\).

Answer 3

Also, remember that the tangent value may be negative. In this case, apply the four quadrant rule on the final answer.

Answer 4

I don't think he wants to see how to solve this. Just want an answer.
