Problem 3: Derive an expression for Vout in terms of Vi and V2; op amps are ideal.
Hint: Consider each op-amp with its respective feedback circuit individually in terms of the classic op-amp circuits we covered in the lectures or using ideal op-amp circuit analysis techniques (mainly KCL) and work your way through the circuit from the inputs to the output.
