This trigonometry table gives the exact and decimal values of sine, cosine and tangent for the common angles (0°, 30°, 45°, 60°, 90° and beyond) in both degrees and radians — the values you need most in geometry and physics.
| Angle | Radians | sin | cos | tan |
|---|---|---|---|---|
| 0° | 0 | 0 | 1 | 0 |
| 30° | π/6 | 1/2 = 0.5 | √3/2 = 0.866 | 1/√3 = 0.577 |
| 45° | π/4 | √2/2 = 0.707 | √2/2 = 0.707 | 1 |
| 60° | π/3 | √3/2 = 0.866 | 1/2 = 0.5 | √3 = 1.732 |
| 90° | π/2 | 1 | 0 | undefined |
| 180° | π | 0 | −1 | 0 |
