• A) \(t = - \frac { 3 \pi } { 2 }\) corresponds to the point \(( x , y ) = ( 0,0 )\) . \(\begin{array} { l }
• \sin \left( - \frac { 3 \pi } { 2 } \right) = 0 \\\\
• \cos \left( - \frac { 3 \pi } { 2 } \right) = 0 \\\\
• \tan \left( - \frac { 3 \pi } { 2 } \right) = 0
• \end{array}\)
• B) \(t = - \frac { 3 \pi } { 2 }\) corresponds to the point \(( x , y ) = ( 1,0 )\) . \(\begin{array} { l }
• \sin \left( - \frac { 3 \pi } { 2 } \right) = 1 \\\\
• \cos \left( - \frac { 3 \pi } { 2 } \right) = 0 \\\\
• \tan \left( - \frac { 3 \pi } { 2 } \right) = 0
• \end{array}\)
• C) \(t = - \frac { 3 \pi } { 2 }\) corresponds to the point \[( x , y ) = ( 0,1 )\] . \[\begin{array} { l }
• \sin \left( - \frac { 3 \pi } { 2 } \right) = 1 \\\\
• \cos \left( - \frac { 3 \pi } { 2 } \right) = 0\\\\
