A calculus and geometric question. The area bounded by the small loop of the limacon r=12sinθ is given by the definite integral. The answer given is ∫(12sinθ)^2 dθ with a lower limit of pi/6 and an upper limit of pi/2. I know how to work out the limits but I can't get the result of (12sinθ)^2. Help!
