For this problem,

The solution is,

I don't understand how they got from ##\frac {sin^2\theta_i}{sin2\theta} ## to ##\frac{tan\theta_i}{2}##. Would somebody please show me the immediate steps?

I also don't understand is why they say the ignore the trivial case where ##\theta_i = 0~rad##. Isn't it implied that ## \theta > 0## if ## R = 3h_{max}##?

Many thanks!

Many thanks!
