Homework Help: Fresnel Equation math problem

  1. Jul 27, 2005 #1
    I am trying to derive the Fresnel equations for the E field perpendicular to the plane of incidence.

    There is one transformation, I assume involves some general math, that I am having a mental blank on.

    It can be found here http://physics.tamuk.edu/~suson/html/4323/prop-em.html if you scroll down to Equation 7.17, they simply state that combining it with Equation 7.14 you can achieve 7.18, the fresnel equation.

    I assuming this is just some substitution and re araging but for the life of me I am unable to figure out how they did. it.

    Enlighten me.
