Find a cofunction with the same value as the given expression.
-$\cos 8 ^ { \circ }$
A) $\sin 82 ^ { \circ }$
B) $\sin 8 ^ { \circ }$
C) $\sec 8 ^ { \circ }$
D) $\csc 82 ^ { \circ }$

Question

Quizplus · Accepted Answer

The cofunction identity states that $\sin(90^\circ - \theta) = \cos(\theta)$. Therefore, $\sin(82^\circ) = \cos(8^\circ)$, making option A correct.
