help with Electrical Engineering HW

my guess is putting it in phasor domain but i wouldn't know what to do after i simplified the circuit (with impedance values).

Well first you need to find the time-domain voltage over the capacitor using phasor domain techniques. After you solve the magnitude of the current through the capacitor, consider whether the source voltage is sinusoidal with a magnitude (not rms) of Vs, your answer should be in the phasor domain (in terms of the frequency).

You must use phasor analysis.

Everytime I see the word "phasor", I think of the Moonraker Laser from Goldeneye.

While doing EE homework alone, I always found it best to have an electronic micro-simulator program open for quick reference. You can just switch in parts, values and make your own nodes and just hit the RUN button. Once confirmed, you just have to go about showing your work to get there instead of answering blindly. Something like PSPICE or MicroLab (think it was called that). Obv best to do homework with friends in your program, teamwork makes it a hundred times easier for everyone.

FWIW I got an A in that class and don't remember enough to solve even a simple Q. Kinda makes me sad.

And +1 on ckt sims to check work.

its been a while but i think it goes something like this?
H = Vo/Vin
Vo = Zc||Zrx = ZrxZc/(Zrx+Zc) = Zrx/(ZrxZc+1)
Vin = Zr4 + Zrx/(ZrxZc+1)
H = Zrx/(ZrxZc+1) / [Zr4 + Zrx/(ZrxZc+1)]
= Zrx / [Zr4ZrxZrc + Zr4 + Zrx]
then sub in Zr4 = R4, Zc = 1/jwC and Zrx = Rx and you get the transfer function
better check with someone else since im not 100% sure

wow so many electric engineers here

EE power!
Simulating the problems is a really good idea, wish I had though of that back in uni

damn I wish this was a statistics question
