Assuming that variables \( a, b, c, d \) and \( f \) are scalars. write MATLAB statements too compute and display the following expressions. Test your statements for the values \( a=1.12, b=2.34, c=0.72, d=0.81 \) and \( \mathrm{f}=19.83 \)
\[
x=1+a / b+c / f^{\wedge} 2, s=b-a / d-c, r=1 / 1 / a+1 / b+1 / c+1 /
\]
\( d, y=a b 1 / c^{*} f^{\wedge} 2 / 2 \)
