z=cos(pi/6)+isin(pi/6)=?

If z = cos"" pi/4+ isin (pi/6) ,then

[[cos(pi)/(5)-i sin(pi)/(5)]]^(-5)

z=5(cos((7pi)/6)+isin((7pi)/6))=?

z=(1-i)/(cos(pi/3)+i sin(pi/3))

z = (1+cos6 pi)+i sin6 pi

If z= cos (pi)/(3) - i sin (pi)/(3) then z^(2)-z+1 is equal to

If z=1+cos((pi)/(5))+i sin((pi)/(5)) then sin(argz) is equal to

One of the value of ("cos"(pi)/(6) +i "sin"(pi)/(6))^((1)/(2)) + ("cos"(pi)/(6)- i "sin"(pi)/(6))^((11)/(2)) is
