Question 4. Refer to the op amp circuit in Fig. 1. Let vin = sin (wt) as shown in Fig. 2. Assume that

Vin does not violate the op amp's common mode voltage input range, and that out is linear. Draw on

Fig. 2's Vout plot the output voltage signal you would expect to see at op amp U1's output pin. Indicate

Vout's amplitude and out's approximate phase angle relative to vin's phase angle.
