complex Numbers

Posted April 3rd, 2011 by alpha

The value of arg(i $w$ )+ arg (i $w^2$ )= $\pi +3 arg \omega$
is
$arg i=\frac{\pi}{2}$ $arg \omega=\frac{2\pi}{3}$
$arg z_1z_2=argz_1+arg z_2$

I need quick answers please coz i'm having test ahead.

It is correct that the $arg i=\frac{\pi}{2}$ , then how could u claim the arg. of w to be 2pi/3 ?
