I found the impedance of the capacitor to be .025j. I found the voltage to be 4.924-.868j. I then divided voltage by total resistance, and converted back to the time domain to get 5sin(20t+9.707deg) for ic(t).
Does this look correct so far?

An image of the problem is attached. I need to solve for ic(t) and vc(t) by adding a complex source.

Looking through my notes I found the equation i(t) = i(0)e^(-(R/L)t), which gives me an answer of i(t) = 60/23e^(-15t/11) for the current through the inductor and -60/23e^(-15t/11) through the resistor. I’m not sure if that’s what you meant by initial conditions, or if my answers are correct.
I re-did the calculation and got 60/23 or about 2.61 for the current through the inductor.
Would the new circuit just be an inductor of 11/3H in series with a resistor of 5 Ohms?
For steady state, I believe I have to treat inductors as short circuits.
I’ve simplified the circuit and then used current division and got a current of 55/23A through the inductor. If I did that right, I think this should be the initial current. What would I then do with that to get current...
What’s the process for solving a problem like this though? This is the first RL circuit problem I’ve been assigned to do so I’m pretty lost.
I assume I can replace the two inductors on the right with one inductor with a value of 2/3H.
After that, I have no idea what to do. The closest thing...

I know how to construct a Gray code for k-maps with 2 bits, 3 bits, and 4 bits. I also looked at the Wikipedia page for Gray code that explained how to construct an n-bit Gray code from the Gray code for n - 1 bits.
What I’m still confused about is where to place the bits. Should the bits be...
Im just finishing up my first digital electronics class right now. I know how to design the logic for basic circuits and some slightly more complex ones.
I don’t quite understand how to design actual circuits for a few reasons.

There are two types of finite state machines (at least that I know about), mealy and Moore.
What are the practical differences between them. I understand that mealy machines take the input into account for the output logic, but are the two machines used for different purposes? Or can the same...
Why are they then reporting the value given from the above equation as the +/- value in the attached image? Doesn’t this imply a symmetry? The value can be anywhere between the value + the uncertainty and the value - the uncertainty.
