Help with Keplers Equation

  1. May 12, 2010 #1
    1. The problem statement, all variables and given/known data
    The question is pretty basic, but for some reason I cant find a way to do it.

    I just need to find out what Eo is.

    I am given nTo= Eo-(2/7)sin(Eo)
    n=1 rad/tu
    To = 2.146 tu

    2.146 rad = Eo - (2/7)sin(Eo)

    2. Relevant equations

    3. The attempt at a solution

    I tried to factor out Eo.

    2.146 = Eo(1-(2/7)sin(theta).
    but obviously that doesnt work.

    It's a transcendental equation involving the unknown in an essentially non-algebraic way. You will need to solve it numerically.
