    Find the transfer function of this circuit. Attempt:

    Vout/Vin = (z2/(z2 + C))

    z2 = R//C

    z2 = ((R.(1/(jwC)) / R + (1/(jwC)))

    = (R + (1 + jwRC))

    So transfer function =

    (R/1+(jwRC) / (1/(jwC) + (R/(1+jwRC))
    I can't get passed this point, can anyone help?

    I'm not sure what you did with your first step of finding z2, but your parenthesis are misbalanced, and I don't think it is correct

    R || C = 1 / ( (1 / R) + (1 / (1/jwC)))
    = 1 / ( (1/R) + jwC)
