Homework Statement
In this task I have $$\frac{tana}{tanb}=c$$ (I know c)
In this task I am looking for $$\frac{sina}{sinb}=?$$
2. The attempt at a solution
I tried transforming the first equation using trig identities. I got this far and got stuck:
$$\left(\frac{tana}{tanb}\right)^{2}=\frac{(sina+sinb)\cdot (sina-sinb)}{sin^{2}b\cdot cos^{2}a}+1$$
Is there a trick to get from this to the fraction I am looking for?
(Please note this is a part of a bigger task and I don't know if it is even solvable).
