    Sinusoidal function

    Hi all,

    New to the forum, hope i posted this in the correct place.

    Got a problem that a question that im struggling to answer:

    draw a waveform over 1 cycle.
    indicate clearly the amplitude, periodic time, and frequency of the waveform.

    v = Vsinωt

    V = 10
    ω = 30pi


    I understand that V is the amplitude of the wave.
    But get confused with the whole omega = 30pi. Mostly because I find pi-radians hard to understand.

    Any help would be much appreciated!!

    Thanks,
    Chris

    If the frequency is f hertz then your signal would be:

    v(t)=V\sin(2\pi f t)

    what you have is:

     <br />
v(t)=V\sin(\omega t)

    so: f=\omega/(2\pi)
