Area Using Polar Coordinates
Polar Integral Formula
area between the graph of
r = r(θ) and the origin
and also between the rays θ
= α and θ = β is given by the formula below
(assuming α ≤ β).
Find the area of the region bounded by
the graph of the lemniscate r2 =
2 cos θ,
the origin, and between the rays θ = –π/6
and θ = π/4.
