$(0,-3)$ is $(3,(3pi)/4)$ in polar coordinates

$(r,theta)$ in polar coordinates is $(rcostheta,rsintheta)$ in rectangular coordinates and

$(x,y)$ in rectangular coordinates is $(sqrt(x^2+y^2),arctan(y/x))$ in polar coordinates.

As such, $(0,-3)$ in rectangular coordinates will be

$(sqrt(0^2+(-3)^2),arctan((-3)/0))$ or

$(3,(3pi)/4)$ in polar coordinates.
