I want to get a transfer function of the following LC low-pass filter.
And, I want to know how it's cut-off frequency is derived.
Thanks for your help.
An LC low-pass filter:

(The first one, the Ui(jw) is at left for input and Uo(jw)) is the output at right.)
The first circuit.
What is the expression for G(jw) = Uo(jw) / Ui(jw)?
And What is the cut-off frequency wc?
{the value wc makes G(jwc) = 1/sqrt(2) * G(j0) }
