4. (a) (10 points) For the circuit below, find the differential equation for v(t), for t 2 0, using the operator method. You are NOT being asked to find the solution, but just setup the differential equation in the following form: d²v(t) dv(t) +A + Bv(t) = f(t) dt dt² C L elle +v(t)- 3u(t)+2 A + R ww
4. (b) (10 points) For the circuit above, find v(t-0') and dv/dt at t-0".
