a. Define the first order differential equations using the state variables i.e.,

x.(t) = A(t) x(t) + B(t) r(t)

b. Define a state variable model for the system in a matrix notation.

c. Use the state space mode to find the transfer function using the following formula:

Y(s)/R(s) = C(SI - A)-1B + D
