Problem 43 Easy Difficulty
Use a CAS to perform the following steps to evaluate the line integrals.
a. Find $d s=|\mathbf{v}(t)|$ d $t$ for the path $\mathbf{r}(t)=g(t) \mathbf{i}+h(t) \mathbf{j}+k(t) \mathbf{k}$.
b. Express the integrand $f(g(t), h(t), k(t))|\mathbf{v}(t)|$ as a function of the parameter $t$.
c. Evaluate $\int_{C} f d s$ using Equation (2) in the text.
$f(x, y, z)=\sqrt{1+30 x^{2}+10 y} ; \quad \mathbf{r}(t)=t \mathbf{i}+t^{2} \mathbf{j}+3 t^{2} \mathbf{k}$
$0 \leq t \leq 2$
