Describe the motion of a particle with position (x, y) as t varies in the given interval. (For each answer, enter an ordered pair of the form x, y.) 6 + sin(t), y = 5 + 4 cos(t), π/2 s t s 2π x The motion of the particle takes place on an ellipse centered at (x, ) 6,5 . As t goes from T/2 to 2π, the particle starts at the point (x, y) and moves clockwise three-fourths of the way around the ellipse to (x, y)
