Question 6. Consider the surface $S$ defined to be the half of the sphere of radius 4 with $z \ge 0$ and let $n$ denote the normal with positive $z$-component. Consider also the vector field $\mathbf{F}(x, y, z) = \begin{pmatrix} y \ -x \ yx^3 \end{pmatrix}$. Use Stokes' Theorem to evaluate the surface integral $\iint_S (\nabla \times \mathbf{F}) \cdot \mathbf{n} \, dS$.
