    Periodic behavior.

    The equation given is this:

    Q(t)=300cos((pi/9)(t))+1500

    and the following question is, "What's the period? Include units."

    I'm not sure how to answer this. As in, I'm not sure how to explain it in words, let alone in context to this equation. Help, please?

    period, T , is time.

    for the cosine and sine functions, T = \frac{2\pi}{B}
