Represent the surface in space, identify the surface-

r=2cos(theta)

2. Relevant equations

Uhh....

3. The attempt at a solution

My main thing here is this... how does r tell me anything about the graph of the function in a 3-D plane? i see that r=2cos(theta) but what does it tell me?? i know that 2cos(theta) = cos^2(t)-sin^2(t), so r= that... now what>??? im honestly stumped here, thats really as far as i can go with what i know.
