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 + 1/(jwC)]. 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.

When you have it in a form that includes a complex quantity (which is just about every case) you take the absolute value, also known as "norm".
This is calculated as follows:
abs(a+b*j)=sqrt(a^2+b^2)
This gives the magnitude.
