Web13. maj 2024. · For the polar curve r = 2 cos ( 3 θ), you can find the area of all three petals by getting the area of one-half petal using the bounds θ = 0 to θ = π /6 for A = ( 1 / 2) ∫ r 2 d θ, and multiplying that by 6. But when you try to get the area of the curve using the bounds θ = 0 to θ = 2 π, the area is incorrect.
