In the above diagram,
i_in(t) = -0.5u(-t) + 2u(t) A
R = 2 Ω
L = 1 H
C = 8 mF
Find the zero-input, zero-state, and complete responses of v_C(t) and i_L(t) for t > 0.
This is what I have so far, and I think it's correct, but I am totally confused as to what I need to do to get the zero-input response. I'm not really sure if I understand it conceptually. I know it (obviously) involves turning off all input sources, but can I do it for any time value?
