Use Simpson's rule to find the arclength of the curve $LaTeX: \displaystyle f(x)=x^{2}$ on $LaTeX: \displaystyle (2,8)$ with $LaTeX: \displaystyle n=34$ .

$LaTeX: \displaystyle \Delta x = \frac{ 8 - 2 }{ 34 }$ . $LaTeX: \displaystyle x_i = a +i\Delta x = 2 + i \frac{3}{17}$ Using the 1,4,2,...,2,4,1 pattern the sum can be written as $LaTeX: \displaystyle x_i$ can be written split into the even and odd terms. $LaTeX: \displaystyle x_k = 2 + (2k-1)\cdot \frac{3}{17}$ for $LaTeX: \displaystyle k=1$ to $LaTeX: \displaystyle k =17$ and $LaTeX: \displaystyle x_j = 2 + (2j)\cdot \frac{3}{17}$ for $LaTeX: \displaystyle j=1$ to $LaTeX: \displaystyle j =16$ . $LaTeX: \displaystyle f(2) +f(8)+4\sum_{k=1}^{17}f\left(\frac{6 k}{17} + \frac{31}{17}\right) + 2\sum_{j=1}^{16}f\left(\frac{6 j}{17} + 2\right)$ . The value is $LaTeX: \displaystyle 60.345$
