Modify and test the script fprintf$\_$test so that it displays a table of three columns: $x,y1(x)$ and $y2(x).$ Let pi$/6$ pi$/4\frac{}{3}\frac{}{2}$ and $y2(x)=x^{**}[sin(x){]}^2.$ Modify the fprintf commands so that the table titles are properly centered. Display $4$ decimal places for $x$ and three decimal places for $y1$ and $y2.$
