" 6.The principal value of argument of "2" (arg "z" ) for "z=1+i tan(3 pi)/(5)" is "

Principal argument of z=-1-i sqrt(3)

The principal argument of 2z^(2)+1-sqrt(3)i=0

The argument of the complex number z=1 + i tan ""(3pi)/(5) is-

Let z be a complex number such that the principal value of argument, argzgt0 . Then argz-arg(-z) is

If z=sqrt(3)-2+i , then principal value of argument z is (where i=sqrt(-1) (1) -(5pi)/(12) (2) pi/(12) (3) (7pi)/(12) (4) (5pi)/(12)

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=sqrt(3)-2+i, then principal value of argument z is (where i=sqrt(-1)-(5 pi)/(12)(2)(pi)/(12) (3) (7 pi)/(12) (4) (5 pi)/(12)
