After completing one revolution starting from the initial line, point A is observed to have coordinates (-\frac{ \sqrt{3} }{2} , \frac{1}{2}) on the unit circle. Using that information, please answer the following questions:

Calculate all 6 values of the trigonometric functions (clearly state the formulae used to calculate these functions).

Given that point \( A \) on the unit circle has coordinates \( \left( -\frac{\sqrt{3}}{2}, \frac{1}{2} \right) \), we can calculate the six trigonometric functions as follows:

1. **Sine (\(\sin\))**:
   \[ \sin(\theta) = y \]
   \[ \sin(\theta) = \frac{1}{2} \]

2. **Cosine (\(\cos\))**:
   \[ \cos(\theta) = x \]
   \[ \cos(\theta) = -\frac{\sqrt{3}}{2} \]

3. **Tangent (\(\tan\))**:
   \[ \tan(\theta) = \frac{y}{x} \]
   \[ \tan(\theta) = \frac{\frac{1}{2}}{-\frac{\sqrt{3}}{2}} = -\frac{1}{\sqrt{3}} = -\frac{\sqrt{3}}{3} \]

4. **Cosecant (\(\csc\))**:
   \[ \csc(\theta) = \frac{1}{y} \]
   \[ \csc(\theta) = \frac{1}{\frac{1}{2}} = 2 \]

5. **Secant (\(\sec\))**:
   \[ \sec(\theta) = \frac{1}{x} \]
   \[ \sec(\theta) = \frac{1}{-\frac{\sqrt{3}}{2}} = -\frac{2}{\sqrt{3}} = -\frac{2\sqrt{3}}{3} \]

6. **Cotangent (\(\cot\))**:
   \[ \cot(\theta) = \frac{x}{y} \]
   \[ \cot(\theta) = \frac{-\frac{\sqrt{3}}{2}}{\frac{1}{2}} = -\sqrt{3} \]

Summarizing the values of the trigonometric functions:

1. \(\sin(\theta) = \frac{1}{2}\)
2. \(\cos(\theta) = -\frac{\sqrt{3}}{2}\)
3. \(\tan(\theta) = -\frac{\sqrt{3}}{3}\)
4. \(\csc(\theta) = 2\)
5. \(\sec(\theta) = -\frac{2\sqrt{3}}{3}\)
6. \(\cot(\theta) = -\sqrt{3}\)
