Find the area of the region that lies inside the curve r=1+cos(theta) but outside the curve r=3cos(theta)
If f is continuous and non negative on the interval α≤θ≤β with 0<β−α≤2π. Then area of the region bounded by the graph of r=f(θ) between the radial lines θ=α and θ=β is
Area bounded by two curves roand ri where ro denotes outside curve and ri denotes inside curve
