Calculate all six trig functions (sin, cos, tan, csc, sec, cot) for any angle. Supports degrees and radians. Also computes inverse trig functions.
| Degrees | Radians | sin | cos | tan |
|---|---|---|---|---|
| 0° | 0 | 0 | 1 | 0 |
| 30° | π/6 | 1/2 | √3/2 | 1/√3 |
| 45° | π/4 | √2/2 | √2/2 | 1 |
| 60° | π/3 | √3/2 | 1/2 | √3 |
| 90° | π/2 | 1 | 0 | undef. |
| 180° | π | 0 | -1 | 0 |
| 270° | 3π/2 | -1 | 0 | undef. |
| 360° | 2π | 0 | 1 | 0 |
To convert degrees to radians: multiply by π/180
To convert radians to degrees: multiply by 180/π
180° = π rad ≈ 3.14159 rad
