Use Simpson's rule to find the arclength of the curve LaTeX:  \displaystyle f(x)=e^{x} on LaTeX:  \displaystyle (2,9) with LaTeX:  \displaystyle n=24 .

LaTeX:  \displaystyle \Delta x = \frac{ 9 - 2 }{ 24 } . LaTeX:  \displaystyle x_i = a +i\Delta x = 2 + i \frac{7}{24} 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{7}{24} for LaTeX:  \displaystyle k=1 to LaTeX:  \displaystyle k =12 and LaTeX:  \displaystyle x_j = 2 + (2j)\cdot \frac{7}{24} for LaTeX:  \displaystyle j=1 to LaTeX:  \displaystyle j =11 . LaTeX:  \displaystyle f(2) +f(9)+4\sum_{k=1}^{12}f\left(\frac{7 k}{12} + \frac{41}{24}\right) + 2\sum_{j=1}^{11}f\left(\frac{7 j}{12} + 2\right) . The value is LaTeX:  \displaystyle 8096.1
