Root Locus Problem
Problem RLocus3

        Assume that you have a system with three poles at s = -1, -2 and -3.  The G(s) for the system is:

G(s) = 5/[(s + 1)(s + 2)(s + 3)]

The system is being controlled in a feedback system as shown below.

Predict step response performance for K = 1, 2, 5, 10, 20, 50
