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

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

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