**Trigonometry Exercises**

In Exercises 97–100, find an angle \( s \) such that \( s \neq t \), \( 0 \leq s < 2\pi \), and \( \cos s = \cos t \).

- **97.** \( t = \frac{\pi}{4} \)
- **99.** \( t = \frac{4\pi}{3} \)

These exercises require knowledge of trigonometric identities and the unit circle. The objective is to find an angle \( s \) within the specified range that shares the same cosine value as \( t \), but is not equal to \( t \).
