Use a cofunction identity to write an equivalent expression. $$\sin \left(\frac{\pi}{6}-\theta\right)$$
Added by Paula D.
Step 1
The cofunction identity states that the sine of an angle is equal to the cosine of its complement, and vice versa. In other words: $$\sin(\theta) = \cos\left(\frac{\pi}{2}-\theta\right)$$ $$\cos(\theta) = \sin\left(\frac{\pi}{2}-\theta\right)$$ Since we have a Show more…
