    A particle moves in a plane with a velocity given by v=(Aωcos(ωt))i^+(Bωsin(ωt))j^\vec{v} = (A\omega cos(\omega t))\hat{i} + (B\omega sin(\omega t))\hat{j}. If the particle starts from the origin at t=0t=0, the equation of the trajectory is:

    A

    x2A2+y2B2=1\frac{x^2}{A^2} + \frac{y^2}{B^2} = 1

    B

    x2A2+(1yB)2=1\frac{x^2}{A^2} + \left(1 - \frac{y}{B}\right)^2 = 1

    C

    x2A2+(yB)2B2=1\frac{x^2}{A^2} + \frac{(y-B)^2}{B^2} = 1

    D

    x2A2+y2B2=2\frac{x^2}{A^2} + \frac{y^2}{B^2} = 2
