From the plot above we have <math>\left(\frac{V_{out}}{_{Vin}} \right)_{max} =  0.0138 </math>
 
 
The bandwidth defined as the width from <math>\omega_1</math> to <math>\omega_2</math> where the amplitude of signal drop down to <math>\frac{1}{\sqrt{2}}</math>.
 
At this point <math>\left(\frac{V_{out}}{V_{in}} \right) =  \frac{0.0138}{\sqrt{2}}  = 0.00976</math>. Let's plot this line and calculate the bandwidth.
