![z1=6(cos\frac{3\pi }{2} +isin\frac{3\pi }{2}) \\z2=[tex]We are to find the argument of z1/z2Since both are in mod, argument form we can use Demoivre theorem for complex numbers to find the quotientQuotient = [tex]\frac{z1}{z2} =\frac{6(cos\frac{3\pi }{2} +isin\frac{3\pi }{2})}{2(cos\frac{5\pi }{6} +isin\frac{5\pi }{6})} \\=\frac{6}{2} (2(cos\frac{4\pi }{6} +isin\frac{4\pi }{6})\\=3 (cos\frac{2\pi }{3} +isin\frac{2\pi }{3})](/tpl/images/0332/1780/2b019.png)
