If `Z =−1 + і` be a complex number .Then `Arg(Z)` is equal to

If Z= -1+i be a complex number .Then Arg(Z) is equal to

If Z=-1+ i be a complex number. Then arg(Z) is equal to O pi O (3pi)/4 O pi/4 O 0

If Z=-1+ i be a complex number. Then arg(Z) is equal to O pi O (3pi)/4 O pi/4 O 0

If Z=-1+ i be a complex number. Then arg(Z) is equal to O pi O (3pi)/4 O pi/4 O 0

If z ne 0 be a complex number and "arg"(z)=pi//4 , then

Let z be any non-zero complex number. Then pr. arg(z) + pr.arg (barz) is equal to

If Z_1,Z_2 and Z_3 , Z_4 are two pairs of conjugate complex numbers then arg (Z_1/Z_4) + arg (Z_2/Z_3) equals:
