Question

\(\sin(-\theta)\) is equal to

• A. \(\cos \theta\)
• B. \(-\cos \theta\)
• C. \(\sin \theta\)
• D. \(-\sin \theta\)

Hint:

Remember that sine is an odd function, so \(\sin(-\theta) = -\sin(\theta)\).

Answer 1

The Correct Option is D

Because sine is an odd function, we have: \[\n\sin(-\theta) = -\sin(\theta)\n\] Therefore, the correct answer is \(-\sin \theta\).
