Find the area of the region bounded by the graph of the polar equation that lies in the specified sector.
r = e^{-Θ/12}, π/2 ≤ Θ ≤ π
Step 1
Recall the formula for a region whose boundary is given by a polar curve r = f(Θ) and by the rays Θ = a and Θ = b.
A = ∫_a^b 1/2 r^2 dΘ
We are given the area bounded by the graph of the polar equation r = e^{-Θ/12} that lies in the sector π/2 ≤ Θ ≤ π.
Therefore, the area of the region bounded by the given polar equation is as follows.
A = ∫_{π/2}^π ( ) dΘ
