question 246

Multiple Choice

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

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