hey, i need help with this please
if w (omega) is a complex root of z^5-1=0
show that w^2 , w^3 and w^4 are the other complex roots.
is this just doing the cis[2k(pi)/n] thing?
and then it says
prove that 1+w+w^2+w^3+w^4 = 0
is this matching the w's to the z's
then doing sometihng like
z^5-1 = 0
(z - 1)(z^4+z^3+z^2+z^1+z) = 0
?
thanks
