# Extract param of $\sin$ from expression $y=2(\sin b-\sin a)/(\sin c-\sin a)$

$$y=2\frac{\sin b-\sin a}{\sin c-\sin a}$$, where

$$a=q(n+0)$$

$$b=q(n+1)$$

$$c=q(n+2)$$

$$q=\frac{2 \pi f}{s}$$

Is it possible to extract $$n$$ from this formula? I already try this on WolframAlpha but I do not know what is C1 and C2 variable

• From what I understood reading your Wolfram link, $c_1$ and $c_2$ can be any integer (they appear on the first steps of the step by step solution). – Ertxiem Apr 16 at 13:53
