$2.$ Consider the following mathematical function:

f$($x$)=($tanh$(2$x$))/(1+$e$^(-1\mathrm{.}5$x$)$cos$(2\backslash$pi x$)$

Write a MATLAB script to plot this function over the interval x Use a solid magenta line for the curve, set the line width to $2,$ and include labels for the x$-$axis, y$-$axis, and a title for the plot.

Show the resulting plot.
