Modify script g$5.$m so that it produces the following $4$ graphs using the subplot option:

$($a$),y=sinh(x)$ from $x=-2$ to $x=+2$ using $51$ points. Use dotted red line of width $2$ only without markers.

$($b$),y=cosh(x)$ from $x=-2$ to $x=+2$ using $51$ points. Use dash$-$dot blue line of width $2$ only without markers.

$($c$)y=si{n}^2(x)$ from $x=0$ to $x=360$ using $51$ points. Use solid green line of width $2$ without markers. The $x$ axis should be in degrees $($not radians$).$

$($d$),y=co{s}^2(x)$ from $x=0$ to $x=360$ using $51$ points. Use dotted black line of width $2$ only without markers. The $x$ axis should be in degrees $($not radians$).$

Label the $x$ and $y$ axis appropriately for each of the $4$ cases. Also, add the function name in the title in each case.
