Question
![### Trigonometric Identity Verification
#### Problem Statement
**d) Verify the identity**
\[
\text{tan}\left(\frac{\theta}{2}\right) = \frac{\sin \theta}{1 + \cos \theta}
\]
In this problem, we are asked to verify the trigonometric identity that involves the tangent of half an angle, \(\frac{\theta}{2}\), and relates it to the sine and cosine of the angle \(\theta\). This is a classic identity in trigonometry and is useful in various contexts such as integration and solving trigonometric equations.
To verify this identity, we will use known trigonometric identities and algebraic manipulation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F39f0d4ee-d4a6-4902-9c76-b777b279390d%2F5b0eca8b-5bec-4a33-843d-09dace5f6cfc%2F676d5n6.png&w=3840&q=75)
