Make a table of at least eight values and then graph $r = 2 \cos θ$ .

Table:

r	θ
	$0$
	$\frac { \pi } { 4 }$
$\sqrt 2$	$\frac { \pi } { 2 }$
	$\frac {3 \pi } { 4 }$

r	θ
	$\pi$
	$\frac {5 \pi } { 4 }$
$0$	$\frac { 3\pi } { 2 }$
	$\frac {7 \pi } { 4 }$

Graph:

Add the rest of the points in your table to complete the graph.

Coordinate axes, with concave down curve, starting at the origin, ending at (1, comma 1),.
