• A)​ \(\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\\\ \cos t = - \frac { 4 } { 5 } \\\\ \tan t = - \frac { 3 } { 4 } \end{array}\) ​
• B)​ \(\begin{array} { l } \sin t = \frac { 3 } { 5 } \\ \cos t = - \frac { 3 } { 4 } \\ \tan t = \frac { 4 } { 5 } \end{array}\) ​
• C) \(\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\\\ \cos t = - \frac { 3 } { 4 } \\\\ \tan t = \frac { 4 } { 5 } \end{array}\) ​
• D)​ \(\begin{array} { l } \sin t = \frac { 3 } { 4 } \\\\ \cos t = \frac { 3 } { 5 } \\\\ \tan t = \frac { 4 } { 5 } \end{array}\) ​
• E)​ \(\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\\\ \cos t = - \frac { 4 } { 5 } \\\\ \tan t = \frac { 3 } { 4 } \end{array}\) ​
