question 42

Multiple Choice

Evaluate (if possible) the sine,cosine,and tangent of the real number.​ $t = - 7 \pi$ ​

• A) \(t = - 7 \pi\) corresponds to the point \(( x , y ) = ( 0 , - 1 )\) . \[\begin{array} { l }
• \sin ( - 7 \pi ) = - 1 \\
• \cos ( - 7 \pi ) = 0\\
• \tan ( - 7 \pi ) ~is~ undefined.
• \end{array}\]
• B) \(t = - 7 \pi\) corresponds to the point \(( x , y ) = ( - 1,0 )\) . \[\begin{array} { l }
• \sin ( - 7 \pi ) = - 1 \\
• \cos ( - 7 \pi ) = 0\\
• \tan ( - 7 \pi) ~is~ undefined.
• \end{array}\]
• C) \(t = - 7 \pi\) corresponds to the point \(( x , y ) = ( 0 , - 1 )\) . \[\begin{array} { l }
• \sin ( - 7 \pi ) = 0 \\
• \cos ( - 7 \pi ) = 0\\
• \tan ( - 7 \pi ) ~is~ undefined.
• \end{array}\]
• D) \(t = - 7 \pi\) corresponds to the point \(( x , y ) = ( - 1,0 )\) . \(\begin{array} { l }
• \sin ( - 7 \pi ) = 0 \\
• \cos ( - 7 \pi ) = - 1 \\
• \tan ( - 7 \pi ) = 0
