Homework Statement
Find the area inside the inner loop of the limacon curve : r = 1 + 2cos(θ)
Homework Equations
A = ∫[itex]\stackrel{α}{β}[/itex]([itex]\frac{1}{2}[/itex]r2)dθ
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]r2)dθ
