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

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

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

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

The principal value of arg(z), where z=1+cos((8 pi)/(5))+i sin((8 pi)/(5))( where i=sqrt(-1) ) is given by

If z=(cos pi)/(4)+i(sin pi)/(6), then |z|=1,arg(z)=(pi)/(4) b.|z|=1,arg(z)=(pi)/(6) c.|z|=(sqrt(3))/(2),arg(z)=(25 pi)/(24)d|z|=(sqrt(3))/(2),arg(z)=(tan^(-1)1)/(sqrt(2))

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

if z = cos ""pi/4 + i sin""pi/6 then

if z = cos ""pi/4 + i sin""pi/6 then
