How to get this expression from the circuit

  1. Apr 14, 2010 #1
    it is given that R1=R2

    i used voltage divider
    i tried to calculate it by taking v1 as the midle poit of the left brench
    and v2 as the middle point of the of the other branch

    so Vout=V_s/2 -Vs[r/(r+1/jwc )=v_s/2(1-rjwc/2(rjwc+1))

    i cant get the expression in the photo
