# Product Of Sines

Geometry Level 4

$\large\sin\dfrac{\pi}{7}\sin\dfrac{2\pi}{7}\sin\dfrac{3\pi}{7}\sin\dfrac{\pi}{14}\sin\dfrac{3\pi}{14}\sin\dfrac{5\pi}{14}$

If the value of the above product can be written in the form of $$\dfrac{\sqrt {a}}{b}$$, where $$a$$ and $$b$$ are coprime positive integers, find $$a+b$$.
