## Cosine Function
### Definition
In a right triangle, **cos(angle) = adjacent / hypotenuse**.
On the unit circle, cos(angle) is the x-coordinate of the point at that angle.
### Key Values
| Angle | cos |
|-------|-----|
| 0° | 1 |
| 30° | √3/2 ≈ 0.8660 |
| 45° | √2/2 ≈ 0.7071 |
| 60° | 0.5 |
| 90° | 0 |

Ejemplo Resuelto
Calculate cos(60°).
- cos(60°) = 0.5
- sin(60°) = √3/2 ≈ 0.8660
- tan(60°) = √3 ≈ 1.7321
