  * Use V<sub>cc</sub>=9V
  * Determine the output V<sub>out</sub> in terms of the inputs V<sub>1</sub>, V<sub>2</sub>, V<sub>3</sub>
  * Build the circuit and verify the functionality. Make sure that V<sub>1</sub>, V<sub>2</sub>, V<sub>3</sub> are always connected to inputs in their respective valid ranges
  * Try out the following
    - V<sub>3</sub>=0V, V<sub>1</sub>=1Vcos(wt), vary V<sub>2</sub> and observe the output on the scope. What is a possible application of this arrangement?
    - V<sub>2</sub>=0V, V<sub>1</sub>=1Vcos(wt), vary V<sub>3</sub> and observe the output on the scope. 
    - V<sub>3</sub>=0V, V<sub>1</sub>=V<sub>2</sub>=2Vp(wt), where p(wt) is a triangular wave. Observe the output on the scope.
