Write a local function named integration to numerically integrate the tabulated values by using trapezoidal rule, if X and Y values are user input and difference between any two consecutive X values is same. Use the above local function to determine $\int_0^\pi y \ dx$ by using following tabulated data. \begin{tabular}{|c|c|c|c|c|c|c|c|} \hline x & 0 & $\pi/6$ & $\pi/3$ & $\pi/2$ & $2\pi/3$ & $5\pi/6$ & $\pi$ \\ \hline y & 0 & 0.5 & 0.866 & 1 & 0.866 & 0.5 & 0 \\ \hline \end{tabular} Validate the result by using appropriate built-in function in MATLAB

For Problems 8-12, let $\vec{r}(t) = (3t, t^3, 3t^2)$ and let $C$ be the curve determined by $\vec{r}(t)$. Problem 9. a) Find the derivative $\vec{r}'(t)$. b) Set up, but do not evaluate, an integral which is equal to the length of the curve $C$ between the points corresponding to $t = 0$ and $t = 3$. Problem 10. Find a general formula for the curvature $\kappa(t)$ of $C$ at the point corresponding to time $t$. You may use the fact that $\vec{r}'(t) \times \vec{r}''(t) = \sqrt{(54t)^2 + (18t)^4 + 18}$, and you do not have to simplify this expression further.
