Multiple Choice

Evaluate (if possible) the sine, cosine, and tangent of the real number. $t = \frac { 3 \pi } { 2 }$

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