Is there a way to tell if an equation is a cardioid or a limacon without graphing it? I'm supposed to tell what shape r=2+2sin theta is, but cardioid and limacon equations look the same. I know cardioids come from limacons, so maybe I should say that.

Not quite, you need to know what the equations look like, cardoids are as the following \[r = a \pm a \cos \theta~~~\text{and}~~~r = a \pm a \sin \theta\] |dw:1434418408816:dw| see if you can figure out these graphs. And limacons are in the following form \[r = b+a \cos \theta~~~\text{and}~~~r = b + a \sin \theta\] horizontal and vertical respectively. And they can be looped, if b
