Find the circulation and flux of the field F = 4x²i+ 4y²j around and across the closed semicircular path that consists of the semicircular arch r₁ (t) = (a cost)i + (a sin t)j, 0≤ts, followed by the line segment r₂(t)=ti, -astsa.
The circulation is 0 (Type an exact answer, using it as needed.)
The flux is (Type an exact answer, using as needed.)
