Evaluate both the left-hand and right-hand side of equation 3.16 to demonstrate the validity of Stokes' theorem for this irrotational flow.

a) (∇ × vecF ⋅ dvecS = ∫ (∇ × vecF) ⋅ dvecl)

b) (∇ ⋅ vecF , dV = ∫ vecF ⋅ dvecS)

c) (∇ × vecF , dV = ∫ vecF ⋅ dvecS)

d) (∇ ⋅ vecF ⋅ dvecS = ∫ (∇ × vecF) ⋅ dvecl)
