If z and ω are two complex numbers such that |zω|=1 and arg(z)−arg – InterviewSolution

1.	If z and ω are two complex numbers such that \|zω\|=1 and arg(z)−arg(ω)=3π2, then arg(1−2¯¯¯zω1+3¯¯¯zω) is(Here arg(z) denotes the principal argument of complex number z )
Answer» If $z$ and $ω$ are two complex numbers such that $\| z ω \| = 1$ and $arg (z) - arg (ω) = \frac{3 π}{2},$ then $arg (\frac{1 - 2 ¯ ¯ ¯ z ω}{1 + 3 ¯ ¯ ¯ z ω})$ is (Here $arg (z)$ denotes the principal argument of complex number $z$ )
