e^w =e^(cos ((2π)/3)+isin ((2π)/3))   =e^(1/2) (cos ((√3)/2)+isin ((√3)/2))
$${e}^{{w}} ={e}^{\mathrm{cos}\:\frac{\mathrm{2}\pi}{\mathrm{3}}+{i}\mathrm{sin}\:\frac{\mathrm{2}\pi}{\mathrm{3}}} \\ $$$$={e}^{\mathrm{1}/\mathrm{2}} \left(\mathrm{cos}\:\left(\sqrt{\mathrm{3}}/\mathrm{2}\right)+{i}\mathrm{sin}\:\left(\sqrt{\mathrm{3}}/\mathrm{2}\right)\right) \\ $$
