Homework Statement
if w is the nth root of unity, i.e. w= exp(2pi/n i) show:
[itex](1-w)(1-w^2)...(1-w^{n-1})=n[/itex]
Homework Equations
The Attempt at a Solution
since w^(n-a)= complex congugate of w^a
terms on the left hand side are going to pair up to give [itex]|1-w|^2 |1-w^2|^2...[/itex]
but I'm not sure what to do from here.
Thanks
