It seems that the text extraction did not yield the desired result. Let me analyze the image manually.

The expression in the image appears to be:

$\cos \theta \tan \theta \sec \theta$

Would you like a step-by-step explanation of how to simplify or analyze this expression?

Here are some related questions to consider:

1. What are the relationships between $\cos \theta$, $\tan \theta$, and $\sec \theta$?
2. How can trigonometric identities simplify this expression?
3. How do $\tan \theta$ and $\sec \theta$ relate to $\sin \theta$ and $\cos \theta$?
4. Can this expression be further reduced or transformed into a single trigonometric function?
5. What is the importance of understanding these relationships in calculus or physics?

Tip: Learning the fundamental trigonometric identities is crucial for simplifying complex expressions efficiently.
