![## Vector Calculus Problem Set
### Problem 3
Let \(\mathbf{F}(x, y) = (2xe^y + yz)\mathbf{i} + (x^2e^y + xz)\mathbf{j} + xy\mathbf{k}\).
(a) Find \(\text{Div}(\mathbf{F})\).
(b) Find \(\text{Curl}(\mathbf{F})\).
### Problem 4
Consider the curve parameterized by \(\mathbf{r}(t) = t(t - 2)\mathbf{i} + \sin(t\pi)\mathbf{j}\) for \(t \in [0, b].\)
