You can put this solution on YOUR website! Give a pair of polar coordinates, with 0°<θ <360° and r ≥0, for the point whose rectangular coordinates are (-1,√3).
Enter you answer as an ordered pair.
-------
r = sqrt[(-1)^+(sqrt(3))^2] = sqrt(4) = 2
-------
theta = tan^-1(sqrt(3)/-1) = 60 degrees.
-------------
Ans: (2,60 deg)
