    I need to find V(out) (magnitude only), in the Phasor domain, in terms of the frequency ω and I need to show that the cutoff frequency of this circuit is 1/RC.

    Can any body help me with that..? I will be Grateful.

    This should be posted in the homework forum.

    Do you know what a 3dB down point is? (cutoff frequency)

    Is this project school related?

    Generally cutoff is when the reactance of the capacitor equals that of the resistor (or inductor).
