(1 point) Suppose the unit circle centered at the origin has been labeled as a clock, and time t runs from zero to 2. For each description of the clock hand's movement below, if possible, match it with a parametric equation. Enter the appropriate letter A, B, C, D, E, or F in each blank. A. Starts at 12 o'clock and moves clockwise one time around. B. Starts at 6 o'clock and moves clockwise one time around. C. Starts at 3 o'clock and moves clockwise one time around. D. Starts at 9 o'clock and moves counterclockwise one time around. E. Starts at 3 o'clock and moves counterclockwise two times around. F. Starts at 3 o'clock and moves counterclockwise to 9 o'clock. 1. x = - cos(t); y = - sin(t) 2. x = - sin(t); y = - cos(t) 3. x = cos(2t); y = sin(2t) 4. X = COS y = sin = 5. x = cos(t); y = - sin(t)(1 point) Consider the curve described by the parametric equations: X=7 - + 2 = 6 1+3 + 41 + 2 (a) Find the values of t where the curve intersects itself: (b) Find the area of the region enclosed by the parametric equations.
