$$\begin{array} { l l }
2 \left( \cos \frac { \pi } { 3 } + i \sin \frac { \pi } { 3 } \right) & \square
2 \left( \cos \frac { 2 \pi } { 3 } + i \sin \frac { 2 \pi } { 3 } \right) & \square
2 \left( \cos \left( - \frac { \pi } { 3 } \right) + i \sin \left( - \frac { \pi } { 3 } \right) \right) & \square
