If $arg(z) = \theta$,then $arg(\overline{z}) = $

If the $\operatorname{Arg} z_1$ and $\operatorname{Arg} \overline{z_2}$ are $\frac{\pi}{3}$ and $\frac{\pi}{5}$ respectively,then the value of $\operatorname{Arg} z_1 + \operatorname{Arg} z_2$ is

The amplitude of $0$ is

Convert the given complex number in polar form: $\sqrt{3}+i$

If $z = \frac{(2-i)(1+i)^3}{(1-i)^2}$,then $\operatorname{Arg}(z) = $

If $0 < \text{amp}(z) < \pi$,then $\text{amp}(z) - \text{amp}(-z) = $
