**Trigonometric Analysis of Angle θ**

Given that \( \theta = \frac{4\pi}{3} \) radians is an angle in standard position, find the exact values of the following trigonometric functions:

- \( \sin \theta = \)
- \( \cos \theta = \)
- \( \tan \theta = \)

Additionally, determine the coterminal angles for \( \theta \):

- Positive angle coterminal with \( \frac{4\pi}{3} \)
- Negative angle coterminal with \( \frac{4\pi}{3} \)

**Explanation:**

For the angle \( \theta = \frac{4\pi}{3} \), you are tasked with identifying the exact values of its sine, cosine, and tangent, crucial trigonometric functions that describe its position in the unit circle. Coterminal angles are those that share the same terminal side with \( \theta \) but can be found by adding or subtracting full rotations (\(2\pi\) radians) from \( \theta \).
