Describe the motion of a particle with position P(x, y) when x=2sint, y=2cost as t varies in the interval 0t2 .

1. Moves along the line x/4 + y/2 = 1, starting at (0, 2) and ending at (4, 0).
2. Moves along the line x/4 + y/2 = 1, starting at (4, 0) and ending at (0, 2).
3. Moves once clockwise along the ellips X²/16 + y²/4=1, starting and ending at (0, 2).
4. Moves once clockwise along the ellipse (4X)² + (2y)²=1, starting and ending at (0, 2).
5. Moves once counterclockwise along the ellipse X²/16 + y²/4=1, starting and ending at (0, 2).
6. Moves once counterclockwise along the ellipse (4X)² + (2y)²=1, starting and ending at (0, 2).
