Transcribed Image Text:### Exercise on Trigonometric Functions from the Unit Circle 2
---
#### Task Instructions:
Calculate the values of the following trigonometric functions based on the given angles from the Unit Circle.
---
#### Problems:
1. **Secant Function (sec)**
\(\sec 330^\circ\)
2. **Cosecant Function (csc)**
\(\csc 210^\circ\)
3. **Cosine Function (cos)**
\(\cos 60^\circ\)
---
To find the values of these trigonometric functions, you can refer to the unit circle, where each angle corresponds to a specific point \((x, y)\) on the circle. Remember the fundamental definitions:
- \(\sec \theta = \frac{1}{\cos \theta}\)
- \(\csc \theta = \frac{1}{\sin \theta}\)
- \(\cos \theta = \text{cosine of the angle} \theta\)
Make use of these definitions to determine the values accurately. Happy solving!
