In order to tell what kind of graph you have, you look at the equation.
If the equation is r = a + b sin θ OR r = a + b cos θ, then you have a limacon.
If the equation is r = a - b sin θ OR r = a - b cos θ, then you have a cardiod.
If the equation is r = a θ + b, then you have an archimedes spiral whereas if the equation is r = a b ^ θ, then you have a logarithmic spiral.
If the equation is r = a sin(nθ) OR r = a cos(nθ), then it is a rose where n = the number of petals.
