Show how we can get the steady-state value of A(t) for problem 3.48,

in the following two ways:

 (a) Set the time derivatives equal to zero in the Markov equations and and combine with the equation that states that the sum of all the probabilities is unity.

(b) Use the Laplace transform final value theorem.
