Verify that the equation is an identity
![The equation shown is:
\[
\frac{\sin 2\theta}{1 - \cos 2\theta} = \cot \theta
\]
This equation involves trigonometric identities and properties:
- \(\sin 2\theta\) and \(\cos 2\theta\) are double-angle identities.
- \(\cot \theta\) is the cotangent of \(\theta\), which is equal to \(\frac{\cos \theta}{\sin \theta}\).
The equation establishes a relationship between these trigonometric expressions.
This problem likely requires the application of trigonometric identities to verify the equality or to solve for \(\theta\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faef5423c-5a38-44c6-89dc-e100f9cb0f83%2F3786698e-1c4c-4e7b-b5b3-a29cef6c1003%2Fidv5pur_processed.jpeg&w=3840&q=75)
