Homework Statement
The problem is essentially (I've rephrased it, but this is what it is asking)
show that [ (2n1cosa) / (n2cosa + n1cosb) ]2
is equal to (sin2a sin2b) / (sin2(a+b)cos2(a-b))
where these are for refraction through materials and satisfy n1sina=n2sinb
2. The attempt at a solution
I just took pictures of my work because it would be easier than typing it all out. As far as I can tell I didn't do anything wrong up till then

the lines are numbered so you can refer to them easily if you need to
tl;dr:
show how [2cosasinb]2 = sin2a sin2b
Thanks
