What are the polar coordinates of the rectangular coordinates (√3,−1)? (2,5π/6) (4,5π/6) (2,11π/6) (4,11π/6)

If (x, y) are the rectangular coordinates and (r, theta) are the corresponding polar coordinates, then use

 

r2 = x2 + y2 

 

and 

 

tan(theta) = y/x

 

to get from rectangular to polar.
