- Draw $\vec r(t) = (3 \cos t, 3 \sin t)$.
- Find the velocity of an object parametrized by the curve above. Then state the speed. [Hint: derivatives will help.]
- Draw $\vec r(t) = (3 \cos 2t, 3 \sin 2t)$.
- Hurricane Matthew has a diameter of 28 miles. Assuming the eye is at the origin $(0,0)$, give a parametrization of the exterior edge of the hurricane.
- Sustained winds are 128 mi/hr. Modify your parametrization above so that the speed is 128 mi/hr.
- The eye of the hurricane is moving north west at a speed of 12 mi/hr. Modify your parametrization so that the center moves north west at 12 mi/hr.
