    Can someone please explain to me in brief detail as to what each expression means for the given formula:-


    and to how this formula works? It is a formula that has been given to me in order to work out time at which a waveform=V(min) for a dc smoothing circuit with a typical power supply.

    V(in) is a voltage that changes with time. It changes with time in a sinusoidal fashion, with an amplitude of V(max). The angular frequency is w (units: radians/second) or a cycle frequency f=2*pi*w (units: cycles/second or Hz).
