(a) Sketch the root locus of the closed-loop system. Compute the real-axis intercept and angle of the asymptote.
(b) Compute the real-axis break-in or break-away point if applicable. Specify it is a break-in or breakaway point.
(c) Find the gain that is associated with the point you found in the previous step.
