9-70.

For each set of parametric equation in problem 9-69, describe what part of the curve is sketched in each case when $-2\le t\le2$.

The curve will start at $(\ \cos(-2),\ \sin(-2))$, pass through $(\cos(0),\ \sin(0))$, and end at $\left(\cos(2),\ \sin(2))\ \right)$.
Evaluate and graph these points.

The curve will start at $(\cos(-4),\sin(-4))$, pass through $(\cos(0), \sin(0))$, and end at $(\cos(4), \sin(4))$.
Evaluate and graph these points.
