If the operational amplifier in the circuit below is ideal, the input impedance looking into terminal \(V_{in}\) is


An ideal opamp with an infinite gain and infinite bandwidth is connected in feedback as shown below. The output voltage \(V_o\) for the given input voltages in the circuit is ________ V (accurate to one decimal place).

In the circuit shown below, the output voltage \(V_{out}\) is \(\underline{\hspace{1cm}}\) V. 

In the circuit diagram shown below, all OPAMPs are ideal with infinite gain and bandwidth. \(\frac{V_{OUT}}{V_{IN}}\) for this circuit is \(\underline{\hspace{2cm}}\).
