Question
Consider the rose curve below.r = cos(2𝜃)Write an integral that represents the area of the left petal of the rose curve shown in the figure. Do not evaluate the integral. (Use theta for 𝜃 as necessary.) 12 5𝜋4
Solution
The area of a polar curve is given by the integral A = 1/2 ∫[α, β] (r(θ))^2 dθ.
For the rose curve r = cos(2θ), the left petal corresponds to the interval [3π/4, 5π/4] in the polar coordinate system.
So, the integral that represents the area of the left petal of the rose curve is:
A = 1/2 ∫[3π/4, 5π/4] (cos(2θ))^2 dθ.
