11-11.

Using your graph from the previous problem, but without doing any more computations, sketch the graphs of the functions below.

1. $r = 3\cos(θ)$

1. $r = −4\cos(θ)$

The curve in the previous problem was a circle with a diameter of $1$, passing through the origin, on the positive $x$-axis.
