Trigonometry Calculator User Guide
Trigonometry calculator supports sine (sin), cosine (cos), tangent (tan), and inverse trigonometric functions (arcsin, arccos, arctan).
Functions:
- sin(θ) - Sine function, input angle/radian, output ratio
- cos(θ) - Cosine function, input angle/radian, output ratio
- tan(θ) - Tangent function, input angle/radian, output ratio
- arcsin(x) - Inverse sine, input ratio (-1~1), output angle/radian
- arccos(x) - Inverse cosine, input ratio (-1~1), output angle/radian
- arctan(x) - Inverse tangent, input any real number, output angle/radian
Special Values Table:
| Angle | Radians | sin | cos | tan |
|---|---|---|---|---|
| 0° | 0 | 0 | 1 | 0 |
| 30° | π/6 | 0.5 | 0.866 | 0.577 |
| 45° | π/4 | 0.707 | 0.707 | 1 |
| 60° | π/3 | 0.866 | 0.5 | 1.732 |
| 90° | π/2 | 1 | 0 | ∞ |
