(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the area inside the inner loop of the limacon curve : r = 1 + 2cos(θ)

2. Relevant equations

A = ∫[itex]\stackrel{α}{β}[/itex]([itex]\frac{1}{2}[/itex]r^{2})dθ

3. The attempt at a solution

i have the solution, my question is : how do you find α and β ?

here α = 2π/3 and β = π

A = 2∫[itex]\stackrel{2π/3}{π}[/itex]([itex]\frac{1}{2}[/itex]r^{2})dθ
