The parametric equations of the circle x^2+y^2+x+\sqrt3y=0 are

Correct Answer is : x=−12+cosθ,y=−√32+sinθ

x=1+\cos\theta,y=\sqrt3/2+\sin\theta

x=-1/2+\cos\theta,y=-\sqrt3/2+\sin\theta

x=1/2+\cos\theta,y=-\sqrt3/2+\sin\theta

x=1/2+1/2cos\theta,y=-\sqrt3/2+1/2sin\theta

x=\cos\theta-1,y=-\sqrt3/2+\sin\theta
