    RWA of Sine and Cosine

    "If the equilibrium point is y=0, then <br /> <br />
y = -5\cos{\left(\frac{\pi}{6}t\right)}<br />
models a buoy bobbing up and down in the water.

    a) Describe the location of the buoy when t=0.

    b) What is the maximum height of the buoy?

    c) Find the location of the buoy at t=7"

    That's the first question on my assignment. It is simply homework. Not a test. I need help doing this. I am not looking for just the answer. Can somebody please walk me through how this is done? I have 7 problems to do and if I can't even do the first one, I'm skewed. XP


    I had this class on Thursday (4 days ago) and didn't have class on Friday, and it was taught quickly for the last 1/2 of the class so we only spent 20 minutes on it so I really don't even know where to start... I'm trying to think of where I could start to the point of making my head hurt.. It's really frustrating...

    Thank you very much.

    P.S. I tried using LaTex for this but Im new to it and couldn't get it to work.. But Im trying....
