Homework Statement
The question involves the fresnel equations which I have derived. However, I seem to be missing something in the simplification. I arrive at these:

and I am trying to simplify to:

The Attempt at a Solution
No matter how I use snell's law I can't seem to get them to simplify properly. Is there a trig identity that I'm missing? Currently I'm only interested in the coefficients if the field is polarized parallel to the plane of incidence.
Thanks for any input with the mathematics.
