    1. The problem statement, all variables and given/known data

    [Broken]

    Find the transfer function, Vout(s)/Vin(s)

    The (s) signifies the laplace plane

    2. Relevant equations

    [Broken]


    3. The attempt at a solution

    I'm keenly aware there is an error here (at least from comparing with the answer sheet). Can you tell me where I went wrong?

    The voltage divider approach is fine, but pay close attention to where the output voltage is being measured; it's not using the ground (source -ve terminal) as a reference...

    Oh! I used this formula so mechanically already that I forgot what it does and how it functions! Huh... there you go :-)

    Much obliged gneil! Good to know you're (and Nascent!) are still here and kickin' it strong! :)
