sentence1: How can I design an op - amp circuit that can solve the equation y = x ^ 3 + double integral of 4xdx + -LSB- -LRB- e ^ -LRB- -3 x -RRB- +1 -RRB- / -LRB- e ^ -LRB- 2x -RRB- +2 -RRB- -RSB- +5 ?
sentence2: Can you solve the system of equations for -LSB- math -RSB- x + y = -3 -LSB- / math -RSB- and -LSB- math -RSB- x - y = -5 -LSB- / math -RSB- ?
