    Problem: Derive an expression for the gain Vout/Vin. Express your answer in the form of A+jB.

    I know that If C is the capacitor in series with R1, gain = 1 + R2/(R1 - j/wC). It says to express it in the form of A (real)+ jB (imaginary), but I'm not sure how to make the conversion from my solution of gain to the form of A+jB.
    Any help is appreciated.

    I managed to solve it... just kept forgetting to add the 1 to my real part.
