    Periods and phase shift?

    Let .
    What is the amplitude?
    What is the period?
    What is the phase shift?

    I put 3pi as my period because I believe it would be 2pi/6pi which is 3 pi?
    and the phase shift I thought it was 6e4, but thats wrong and I don't know why ?

    Re: Periods and phase shift?

    y = A\sin(Bx + C) + D

    |A| = amplitude

    \frac{2\pi}{|B|} = period

    \frac{C}{B} = phase shift

    D = vertical shift


    btw, work on your division skills ...

    \frac{2\pi}{6\pi} = \frac{1}{3}

    Yes my division was off, but I am unable to get the phase shift would it not be 6e^4 over 6pi ?

    \frac{e^4}{\pi}

    were you also required a direction for the phase shift?

    Re: Periods and phase shift?

    I was not required to give a direction just the value of the phase shift

    Re: Periods and phase shift?

    try -\frac{e^4}{\pi} ... see what happens
