The solution of the equation should have two components:
the transient response vt(t) & the steady-state response vss(t):
·The transient response it is the same as that for source-free case
·The steady-state response is the final value of i(t).
Ø    iss(t) =  i(∞) = Is 
·The values of A1 and A2 are obtained from the initial conditions:
Ø    i(0) and di(0)/dt.
