x = rcos(theta)
y = rsin(theta)
r=sqrt%28x%5E2%2By%5E2%29
r=sqrt%283%29
1=sqrt%283%29sin%28theta%29 -sqrt%282%29=sqrt%283%29cos%28theta%29
1%2Fsqrt%283%29=sin%28theta%29 -sqrt%282%2F3%29=cos%28theta%29
theta+=+arcsin%281%2Fsqrt%283%29%29 theta=arccos%28-sqrt%282%2F3%29%29
theta+=+0.615479709rad

(r,theta) = (sqrt%283%29, 0.615479709)
