Graphing polar functions produces intricate curves so it is best to graph them by plotting points. (cr: eHow)

you have to substitute several values of θ to your polar equation to find r..

θ 0deg 30deg 45deg 60deg ... 360deg

r

as for relative points to make the graphing a little easy...

you can find the graph of r=2+2cosθ in that site..

RE:

How do I graph cardioid r = 2 + 2cosθ?

Just beginning to learn radians and I have no idea how to graph cardioid r = 2 + 2cosθ on a polar grid. How do you do it? (step by step please, i'm a newbie)
