Question

Assume time t runs from zero to and that the unit circle has been labled as a clock. Match each of the pairs of parametric equations with the best description of the curve from the following list. Enter the appropriate letter (A, B, C, D, E, 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 = - sin(t); y = - cos(t) 5. x = cos t/2; y = sin t/2
