The tangent function is the ratio of the opposite side to the adjacent side in a right triangle. Placed in a Cartesian coordinate system $$ tan\theta =y/x $$
Tan takes a corner and returns the ratio of the two right-angled sides of the right-angled triangle. This ratio is the ratio of the length of the opposite side of the corner to the length of the adjacent side in a right triangle.
When used, the calculation form is as follows:
$$ y=tangent(x) $$
| X(deg) | X(Rad) | tangent(X) |
|---|---|---|
| 180 ̊ | π | 0 |
| 150 ̊ | 5π/6 | -0.57735 |
| 135 ̊ | 3π/4 | -1 |
| 120 ̊ | 2π/3 | -1.732051 |
| 90 ̊ | π/2 | Out of Range |
| 60 ̊ | π/3 | 1.732051 |
| 45 ̊ | π/4 | 1 |
| 30 ̊ | π/6 | 0.57735 |
| 0 ̊ | 0 | 0 |
