Lesson goal: Sin, cos and circles

Polar plots are fun because interesting curves can be created that would be much harder in $xy$-coordinates. Polar plots are defined by two variables, $r$ and $\theta$. Here, $r$ is the distance from the origin $(0,0)$ and $\theta$ is the angle from the $+x$-axis. We'll make some interesting polar plots here.

Now you try. Try fixing the r= statement.
