Consider the unity-feedback system with the open-loop transfer function

(a) Use Matlab to draw the Bode plots for G( jω), assuming that K = 1.
(b) What gain K is required for a PM of 45°? What is the GM for this value of K?
(c) What is Kv when the gain K is set for PM = 45°?
(d) Create a root locus with respect to K, and indicate the roots for a PM of 45°.
