The equations r = a + b cos theta and r= a

The equations r = a + b cos theta and r= a + b sin theta describe curves known as limacons. When lal = |bl, the limacon is called a cardioid. The limacon has an inner loop if lal < 2|bl.= " the=" limacon=" is="" oval="" shaped="" if="" lal="">2|bl. Match the correct limacon in the figures to the following equation. r = 3- sin theta Choose the correct graph below. JA OC
