Evaluating a Line Integral Evaluate the line integral
\(\int_{C} y^{2} d x+2 x y d y\).
(a) \(C: \mathbf{r}(t)=(1+3 t) \mathbf{i}+(1+t) \mathbf{j}, \quad 0 \leq t \leq 1\)
(b) \(C: \mathbf{r}(t)=t \mathbf{i}+\sqrt{t} \mathbf{j}, \quad 1 \leq t \leq 4\)
(c) Use the Fundamental Theorem of Line Integrals, where C is a smooth curve from (1, 1) to (4, 2).
