1. Analytically determine an expression for the output voltage, $V_{out}$, in terms of the
input voltages, $V_1$ and $V_2$, and the resistances, $R_1$, $R_2$, and $R_F$.
2. Implement the circuit in Figure 5 and verify you results for $V_1 = 5V$ and $V_2 = 1V$.
3. Explain any discrepancies in your results.
$R_F = 20K$
$R_1 = 20K$
$V_1$
$V_2$
$R_2 = 10K$
$V^- = -12V$
$V^+ = +12V$
