Use Simpson's rule to find the arclength of the curve LaTeX:  \displaystyle f(x)=\frac{1}{x} on LaTeX:  \displaystyle (3,7) with LaTeX:  \displaystyle n=34 .

LaTeX:  \displaystyle \Delta x = \frac{ 7 - 3 }{ 34 } . LaTeX:  \displaystyle x_i = a +i\Delta x = 3 + i \frac{2}{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 = 3 + (2k-1)\cdot \frac{2}{17} for LaTeX:  \displaystyle k=1 to LaTeX:  \displaystyle k =17 and LaTeX:  \displaystyle x_j = 3 + (2j)\cdot \frac{2}{17} for LaTeX:  \displaystyle j=1 to LaTeX:  \displaystyle j =16 . LaTeX:  \displaystyle f(3) +f(7)+4\sum_{k=1}^{17}f\left(\frac{4 k}{17} + \frac{49}{17}\right) + 2\sum_{j=1}^{16}f\left(\frac{4 j}{17} + 3\right) . The value is LaTeX:  \displaystyle 4.0057
