The circuit above has a single input (complex exponential time func. that is not switched with no initial conditions.)
Vs(t) = 10*e^(j 3t)
Calculate the current through the inductor i l(t).

Also...

Calculate current for i(t) (below).

Step by step explanation would be amazing and very very helpful/needed

Hi,

To start, did you try using Euler's Formula for the complex exponential yet?

Not yet, would a s-domain transform be an ideal strategy?

Hi,

Well for the first circuit there, if the complex exponential was converted then yes it seems that you could work in the s domain and use superposition. Try that
