The bottom half should read: (1+cos 4 theta)

Ok so this appears to be the `Tangent HalfAngle Identity`. \[\large \tan \frac{x}{2}=\frac{\sin x}{1+\cos x}\]

So we appears to have something that looks like the `right` side of this identity, yes?

If it helps, maybe make a substitution. Let \(\large x=4\theta\) We know that this will simplify down to \(\large \tan \dfrac{x}{2}\). So from here, \(\large x=4\theta\), solve for x/2! :)
