The curve described parametrically by represents which of the following shapes?
The parametric equations for the curve shown are where ranges over . Which function could be equal to?
What is the shape of the curve described by the above parametric equation?
A point moves counterclockwise along the unit circle at constant angular speed . Describe the motion of the point .
Two clowns, Twinkle and Jingle, are throwing pies at each other. Twinkle throws a pie toward Jingle from centimeters away. Its flight path is given by parametric equations where is time in seconds.
Two seconds later Jingle launches an interceptor pie from his location with the flight path Find the value of which will guarantee that the interceptor pie will hit its target (the pie thrown by Twinkle).
