Finding half-power frequency.
At DC your power dissipation is 0 (cap is blocking current). At very high freq, power dissipation is 0 (inductor is blocking current). At resonance your power dissipation is
(V^2)/R since the LC is series resonant and behaves like a short, all of the input voltage is across the resistor.
