1. The problem statement, all variables and given/kno(It n data
I need to prove that [itex]\prod_{k=1}^{n-1}2\sin\tfrac{k\pi}{n}=n[/itex]
I just don't know where to start and what type of proof to do.
Is there any help to get? :D
I know this has nothing to do with an equation.
But i have come up with the equation i have to prove after investigating lenths between roots x^n=1 where x=ℂ.
I wonder if I can somehow connect the factorization of x^n=1 to the proof.
I have no idea what to do, this is why I am asking for help :D
