How do you graph #r=4costheta#?

Set your compass at #r = 2# put the center at the polar point #(2, 0)# and draw a circle.

Explanation:

The above answer assumes that you have polar graph paper and a drafting compass.

If you convert to the given equation to rectangular form, you discover that it is a circle with its center a #(2,0)# and a radius, #r = 2#

#(x - 2)^2 + y^2 = 2^2#

But I gave you the answer with the center point in polar coordinates.
