Best ResponseYou've already chosen the best response.0But the book says : cos (  2pi/3 ) + i sin (  2pi/3). Which is also right...

Best ResponseYou've already chosen the best response.1So \[=\sqrt{(\frac{ 1 }{ 2 })^2+(\frac{ \sqrt{3} }{ 2 })^2}\]

Best ResponseYou've already chosen the best response.1Drawing it gives you a way better picture of what the angle is.

Best ResponseYou've already chosen the best response.0\[\large{\sqrt{ (\frac{1}{2} )^2 + ( \frac { \sqrt{3}}{2})^2}}\] right so it is : \(\1\)

Best ResponseYou've already chosen the best response.0By the diagram I think that the angle theta will surely lie in the III quadrant i.e. 4 pi /3
