Homework Equations
Uhh...
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>? I am honestly stumped here, that's really as far as i can go with what i know.
