If `z = cos(pi/4) + i sin(pi/6)` , then

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

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

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

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

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

If z_(1) = sqrt(2)(cos""(pi)/(4) + "" i sin""(pi)/(4)) and z_(2) = sqrt(3)(cos""(pi)/(3) + i sin""(pi)/(3)) , then |z_(1)z_(2)| is

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

If z=6(cos(2(pi)/(7))+i sin(2(pi)/(7))) and w=3(cos(5(pi)/(7))+i sin(5(pi)/(7))) then what is the value of (z)/(w)

cos((pi)/(4)+A) cos((pi)/(4) - B) + sin ((pi)/(4) +A) * sin((pi)/4-B)=
