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

Ejemplo Resuelto
Calculate sin(30°).
- 30° in radians = 30 × pi/180 = pi/6 ≈ 0.5236
- sin(30°) = 0.5
- cos(30°) = √3/2 ≈ 0.8660
- tan(30°) = 1/√3 ≈ 0.5774
