I am having a difficult time solving the question in Step 2 of the attachment. The question is "Use the equivalent-circuit model of the uA 741 to find: The voltage gain Av=vo/v1, the input resistance R1, and the output resistance Ro of the amplifier circuit.
Attempt at solution:
I used the equivalent circuit model of the uA 741 to create two equations. My understanding is that I solve for V1 in the first equations and substitute it into the second equation to get the voltage gain Av=Vo/V1, where Vs is V1 in my equations. The problem I am having is how am I supposed to find the input and output resistance, where I don't know V1,
