Find the area of the region that is bounded by the given curve and lies in the specified sector.3. r = sin θ + cos θ, 0 ≤ θ ≤ π

To determine

To Find: The area of the region that lies in the specified sector r=sinθ+cosθ,0θπ.

Explanation

Given:

The polar equation is r=sinθ+cosθ which tends to 0θπ.

Calculation:

Write the formula for area, A as below.

A=ab12r2dθ=0π12(sinθ+cosθ)2dθ

Substitute 1+sin2θ for (sinθ+cosθ)2
