Evaluate
$\sum_{{k = 1}}^{13} \frac{\sin (30^{\circ} k + 45^{\circ})}{\sin (30^{\circ} (k - 1) + 45^{\circ})}$
Put $30^{\circ} = α, 45^{\circ} = β$ . Then
$S = \sum_{{k = 1}}^{13} \frac{\sin (α k + β)}{\sin (α (k - 1) + β)} = \sum_{{k = 1}}^{13} \frac{\sin (α (k - 1) + β + α)}{\sin (α (k - 1) + β)}$
$= \sum_{{k = 1}}^{13} \frac{\sin (α (k - 1) + β) \cos α + \cos (α (k - 1) + β) \sin α}{\sin (α (k - 1) + β)}$
$= \cos α \sum_{{k = 1}}^{13} 1 + \sin α \sum_{{k = 1}}^{13} \cot (α (k - 1) + β)$
$= \frac{\sqrt{3}}{2} \cdot 13 + \frac{1}{2} \sum_{{k = 1}}^{13} \cot (α (k - 1) + β)$
Could some help me to solve it, thanks.

Dual of the formula for Euclidean triangles
It’s well known that the trigonometric area formula for Euclidean triangles is
$S = \frac{1}{2} a b \sin C$ (1.1)
Is there a such formula for hyperbolic triangles?
Is there a proof for (1.1) by using law of cosines?
