Analyze each of the following circuits by assuming that the op-amp is ideal (i.e., V_+ = V_-) and that neither V_i nor V_o is limited by the power supply voltages (i.e., the positive power supply voltage is much greater than either V_i or V_o, and the negative power supply voltage is much less than either V_i or V_o).

Determine the ratio V_o\over V_i for each circuit.

1) Part 1

Enter a Python expression for the ratio V_o\over V_i in terms of R_1, R_2 or constants.

{V_o\over V_i} =~

2) Part 2

Enter a Python expression for the ratio V_o\over V_i in terms of R_1, R_2 or constants.

{V_o\over V_i} =~
