H9P1:
(5)L=55.0H and C=7.37mF. The current source puts out an impulse of area A=2/π=0.64 Coulombs at time t=1.0s.

At t=0 the state is: vC(0)=0.0 and iL(0)=1.0.

The equation governing the evolution of the inductor current in this circuit is

d2iL(t)dt2+1LCiL(t)=ALCδ(t−1.0)
At the time just before the impulse happens what is the voltage vC(1.0−), in Volts, across the capacitor?
