Solving trigonometric equation

  1. Jan 30, 2009 #1
    Hi guys,

    I need to solve the following trigonometric equation. Some time ago I would have used Fortran with the appropriate libraries but now I was wondering whether there is any better approach. Any suggestion?

    w^2/c^2= k//^2 - Sqrt(w^2 Eps_b^2/c^2 - k//^2) * Tan[Sqrt(w^2 Eps_b^2/c^2 - k//^2) * d/2]

    c= speed of light in vacuum
    k//= variable
    d= parameter
    w= frequency
    Eps_b= parameter

    I need to plot w(k//) keeping in mind that "c", "d" and "Eps_b" are just parameters.
