A lifting surface has a spanwise circulation distribution of Γ(θ)=A sin 3θ (where A≠0) over its span -b/2 ≤ y ≤ b/2, and y=-(b/2)cos θ is the spanwise coordinate.
Furthermore, the downwash varies along the span as ω(θ)=V∞(3A sin 3θ / sin θ). where V∞ is the freestream velocity.
Which one of the following options represents the total lift (L) and induced drag (Di)?
