The following equation can be used to compute values of the variable y as a function of the variable x:

y $=$ be$$ax sin$($bx$)(0\mathrm{.}012$x$4$

$0\mathrm{.}15$x$3+0\mathrm{.}075$x$2+2\mathrm{.}5$x$),$

where a and b are parameters. Use the following steps to define and plot this function.

Step $1$: Get familiar with the command window.

Step $2$: Define the scalars a $=2$ and b $=5.$

Step $3$: Define the vector x with values from $0$ to $/2$ in increments of $$x $=/40.$

Step $4$: Use the above equation to define the vector y in MATLAB using element$$by$$element multiplication.

Step $5.$ Compute the vector z $=$ y$2$ where each element of z holds the square of each element of y$.$

Step $6$: Generate a labeled plot of y and z versus x$.$

Step $7$: Include on the plot a y$$axis label, x$$axis label, and legend $($using help as needed to see how to do this$).$

In your submission, show your MATLAB script and an image of the generated plot.
