The image features a trigonometric expression involving sine and cosine functions. The expression is:

\[ \sin \left( \frac{\pi}{14} \right) \cos \left( \frac{\pi}{14} \right) \]

This expression demonstrates the use of the sine and cosine functions on an angle of \(\frac{\pi}{14}\) radians. 

- \(\sin\) represents the sine function, which is one of the primary functions in trigonometry.
- \(\cos\) represents the cosine function, which is another primary function in trigonometry.
- \(\frac{\pi}{14}\) represents the angle in radians. \( \pi \) (pi) is a mathematical constant approximately equal to 3.14159.

When evaluating or working with this expression, one might apply various trigonometric identities or properties to simplify or further transform the expression depending on the context of the problem or the educational objective. For example, a common approach might involve using product-to-sum formulas or other known trigonometric identities.
