• A)\(t = \frac { \pi } { 3 }\) corresponds to the point \(\left( - \frac { \sqrt { 3 } } { 2 } , - \frac { 1 } { 2 } \right)\).
• B) \(t = \frac { \pi } { 3 }\) corresponds to the point \(\left( \frac { \sqrt { 3 } } { 2 } , - \frac { 1 } { 2 } \right)\).
• C) \(t = \frac { \pi } { 3 }\) corresponds to the point \(\left( \frac { 1 } { 2 } , \frac { \sqrt { 3 } } { 2 } \right)\).
• D) \(t = \frac { \pi } { 3 }\) corresponds to the point \(\left( \frac { \sqrt { 3 } } { 2 } , \frac { 1 } { 2 } \right)\).
• E) \(t = \frac { \pi } { 3 }\) corresponds to the point \(\left( \frac { 1 } { 2 } , - \frac { \sqrt { 3 } } { 2 } \right)\).
