Describe in your own words why: (a) The real parts of the poles of a transfer function determine the stability of a steady state. (Hint: relate the real parts of the poles back to where they appear in the time-domain solution.) (b) The imaginary parts of the poles of a transfer function determine the frequency of oscillations as you approach steady state. (Hint: relate the imaginary parts of the poles back to where they appear in the time-domain solution.)
