The polar coordinates are (2,7/6pi)

Explanation:

To convert from cartesian coordinates (x,y) into polar coordinates, (r, theta) we use the following equations

r=sqrt(x^2+y^2)

tan theta=y/x

r=sqrt((sqrt3)^2+1^2)

=sqrt4=2

tan theta=-1/-sqrt3=1/sqrt3

We are in the 3rd quadrant

theta=pi+pi/6=7/6pi

The polar coordinates are (2,7/6pi)
