You can put this solution on YOUR website! find polar coordinates of each point (-2sqrt3,2)
----
The point is in the 2nd quadrant.
---
theta = tan^-1(2/(-2sqrt(3)) = tan^-1(-1/sqrt(3)) = (5pi/6)
----
r = sqrt[(2sqrt(3))^2 + 2^2]
= sqrt[12+4]
= 4
----
polar coordinates: (4,5pi/6)
===============================
