Need to find the Gain over the whole Circuit: Vo/Vs
Solve G equation for V1 and substitute in for above equ.
We now have an equation for the overall circuit gain
Simplifying and substituting jw for s
If G = 3, oscillations occur
If G < 3, oscillations attenuate
If G > 3, oscillation amplify
G = 2.9
G = 3.05
