The parametric equations define the motion of a particle in the xy-plane. x = 4 cost sts 3.0 y=9 sint A. Identify the particle's path by finding a Cartesian equation for it. B. Graph the path of the particle and indicate the direction of motion traced by the particle. Label at least three points on the particle's path (including all boundary points) with the xy-coordinates as well as the time t.
