If the curve is parameterized by two functions x and y. \[ \begin{align*} \text{Surface Area} &=\lim_{n}\sum_{i=1}n^2f(x^{**}_i)x\sqrt{1+(f(x^_i))^2} \\[4pt] &=^b_a(2f(x)\sqrt{1+(f(x))^2}) \end{align*}\]. What is the arclength of #f(x)=(1+x^2)/(x-1)# on #x in [2,3]#? To find the surface area of the band, we need to find the lateral surface area, \(S\), of the frustum (the area of just the slanted outside surface of the frustum, not including the areas of the top or bottom faces). 2023 Math24.pro info@math24.pro info@math24.pro
