A real value of $x$ will satisfy the equation $\left( {\frac{{3 - 4ix}}{{3 + 4ix}}} \right) = $ $\alpha - i\beta \,(\alpha ,\beta \,{\rm{real),}}$ if
${\alpha ^2} - {\beta ^2} = - 1$
${\alpha ^2} - {\beta ^2} = 1$
${\alpha ^2} + {\beta ^2} = 1$
${\alpha ^2} - {\beta ^2} = 2$
Given $z$ is a complex number such that $|z| < 2,$ then the maximum value of $|iz + 6 -8i|$ is equal to-
The complex numbers $sin\ x + i\ cos\ 2x$ and $cos\ x\ -\ i\ sin\ 2x$ are conjugate to each other, for
If $z$ is a complex number such that ${z^2} = {(\bar z)^2},$ then
If ${z_1}.{z_2}........{z_n} = z,$ then $arg\,{z_1} + arg\,{z_2} + ....$+$arg\,{z_n}$ and $arg$$z$ differ by a
The sum of amplitude of $z$ and another complex number is $\pi $. The other complex number can be written
