Double Angle Sine 8B6A44
1. **Problem Statement:** Evaluate the expression $2 \sin(34^\circ) \cos(34^\circ)$.\n\n2. **Formula Used:** The double-angle identity for sine states that:
$$2 \sin(\theta) \cos(\theta) = \sin(2\theta)$$
This identity allows us to simplify the product of sine and cosine into a single sine function with double the angle.
\n3. **Apply the formula:**
Substitute $\theta = 34^\circ$:
$$2 \sin(34^\circ) \cos(34^\circ) = \sin(2 \times 34^\circ) = \sin(68^\circ)$$
\n4. **Evaluate the sine:**
Using a calculator or sine table:
$$\sin(68^\circ) \approx 0.9272$$
\n5. **Conclusion:**
The value of $2 \sin(34^\circ) \cos(34^\circ)$ is approximately $0.9272$.
\nThis shows how double-angle identities simplify trigonometric expressions by converting products into single trigonometric functions, making evaluation easier.
