For the circuit below, find the magnitude and phase difference in radians between an input sine wave Vin(w) and the output wave Vout(w) as a function of frequency. Plot the magnitude (log-log) and phase (linear-log) as a function of frequency. Vin(w) is across the left ports, Vout(w) is across the right ports.
