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