A system transfer function is given by

\[ T(s)=\frac{K s}{K s^{2}+1} \]

Derive the sensitivity function and determine the value(s) of \(K\) that minimize sensitivity. Plot \(T(s)\) for \(K=1,10,100\) on one set of axes and draw conclusions from the comparison. Plot the sensitivity function for each of the \(K\) values, also on one set of axes. Which value of \(K\) reduces sensitivity?
