A closed-loop system with unity feedback has a transfer function

(a) Determine the loop transfer function Gc(s) G(s).
(b) Plot the log-magnitude-phase (similar to Figure 8.27), and identify the frequency points for co equal to 1,10,50,110, and 500. (c) Is the open-loop system stable? Is the closed-loop system stable?
