Q$3.$ Use the following tabular data a$)$ to evaluate the integral of the f$($x$)$ function from $x=0$ to $x=1\mathrm{.}2$ using the $f(x)$ function at $x=0\mathrm{.}8$ using the Gentered givided gifference Approximatyon.

$\backslash$table$[[x,0,0\mathrm{.}2,04,0\mathrm{.}6,01,,],[f(x),0,\mathrm{.}0\mathrm{.}0367,0\mathrm{.}0007,0\mathrm{.}2100,0\mathrm{.}6533,14167,]]$

$\{\begin{array}{c}\text{:}{f}^{\text{'}}(x_1)=\frac{f(x_1)-f(x_1)}{in}{f}^{\text{'}\text{'}}(x_1)=\frac{f(x_1)-2f(x_1)+f(x_{i-1})}{n^2}\end{array}$
