Let us consider the transfer function

$G(s)=\frac{1}{s^2+33s+90}$

$($a$)$ Find the piece$-$wise linear approximation of $|G(j)|$ in dB and $\frac{?}{{?}_G(j)}$ and plot them roughly. $[3+2$ points$]$

$($b$)$ Use MATLAB bode command to plot the exact frequency response $($i$.$e$.,|G(j)|$ in dB and $\frac{?}{{?}_G(j)}$ and compare it with part $($a$).$

$[5$ points$]$
