    Your attachment is still being approved, but I can tell already that you won't get much help. Work must be shown for anyone to start to help you. What have you done already, laplace transforms, impedences?

    the answer given is [R2/(R1+R2)][jw/(jw+wc)] but my answer is R2jwL/(R1R2 + R1jwL + R2jwL)

    Neither of those makes any sense, the first one less than the second. That looks more like a transfer function than a cutoff frequency.

    Well say what kind of passive filter is this before you move on.
