hey im stuck in this past paper question. would realli lyk help
-------------------------10
i) Find the roots of z = 1 (i can do this part)
-----------------------------10
explain why ( (z-1) / z) = 1 only has nine roots,
show the roots of this equation are
z = 1/2 (1 + i cot (kPI/10) ), k = 1,2,3...,9
