    Finding Equation from Graph

    Hello there

    I am new here and I need your help with my math assignment.

    I have to hand in this assignment tomorrow but I have not figured out how to find the equation from the graph. I know it is a cosine function.
    Do you know of any website or software that figures out equations by X and Y values? How can I convert the time to Radian Angles?

    Y is the height and X is the time in Hours. How can I convert Hours to Radians?. I am really stuck and have only 12 hours left to hand it. so plz help.

    There are lots of requests for help for similar questions on this Forum. For instance, this and this were posted and answered recently.

    Your function has a mean value of 6, an amplitude of 5 and a period of 12. The function is:
    y = 6-5\sin\left(\frac{\pi x}{6}\right)
    If you study the examples above you will perhaps be able to work out why.
