Determine the signs of the given trigonometric functions of an angle in standard position with the given measure.
-$\sec \left( 704 ^ { \circ } \right)$ and $\sin \left( 704 ^ { \circ } \right)$
A) negative and positive
B) positive and positive
C) positive and negative
D) negative and negative

Question

Quizplus · Accepted Answer

$\sec \left( 704 ^ { \circ } \right)$ is positive and $\sin \left( 704 ^ { \circ } \right)$ is negative because $704^\circ$ corresponds to an angle in the fourth quadrant, where cosine (and therefore secant) is positive and sine is negative.
