Problem 5
Orient the curve $C \subset \mathbb{R}^3$ at the intersection of the cone $z^2 = x^2 + y^2$ and the plane $2z = y + 4$, counter-clockwise
(when viewed from above). Calculate the circulation $W_C = \oint_C \mathbf{F} \cdot d\mathbf{r}$ over $C$ in this orientation, for the vector field
$\mathbf{F}(x, y, z) = (4z - 4y, e^{z^4} - 2x, sin(y^3) + 3z)$.
