Polar Equations

posted by .

I am supposed to identify the classical curve that is represented by
r = 1 + sin Theta.

I think it's a cardioid, because its equation is r = 1 + 1 sin theta (r = a + a sin theta). Is this correct?

    that is correct

    wolframalpha . com will draw it for you. Just type in

    plot r = 1 + sin(theta)
