Consider the circuit shown in Figure $6\mathrm{.}77($Review Problems, Problem $4)$

a$.$ Determine a suitable set of state variables and obtain the stase$-$space representation.

b$.$ Find the transfer function directly from the state$-$space form and compare with the result obtained in Problem $4.$

for the circuit shown in Figure $6\mathrm{.}78($Review Problems, Problem $4).$
