Consider a particle following the parametric equations
\begin{align*} x &= 3 + 2 \sin (2t),\\ y &= 4 + 2 \cos (2t). \end{align*}What is the speed of this particle, and what direction is it moving? Put the answers in that order, and answer "CW" for clockwise or "CCW" for counterclockwise.

The speed is 4*pi, moving CCW.
