Use identities to write the expression as a single function of x or θ.
-$\sin \left( 360 ^ { \circ } + x \right)$
A) $\frac { \sqrt { 2 } } { 2 } \cos x + \frac { \sqrt { 2 } } { 2 } \sin x$
B) $\sin x$
C) $- \cos x$
D) $\frac { \sqrt { 2 } } { 2 } \cos x - \frac { \sqrt { 2 } } { 2 } \sin x$

Question

Quizplus · Accepted Answer

The sine function is periodic with a period of $360^\circ$, so $\sin(360^\circ + x) = \sin x$.

Use Identities to Write the Expression as a Single Function sin⁡(360∘+x)\sin \left( 360 ^ { \circ } + x \right)sin(360∘+x)
