| Parameter | Description |
|---|---|
| f | The input angle, in radians. |
float The return value in the range (-Infinity, Infinity).
Returns the tangent of angle f in radians.
The tangent trigonometric function has two properties than are worth considering:
- It has two vertical asymptotes at f = ±π/2. This means that when approaching these f values, the output of the function will grow towards ±Infinity (without ever reaching them).
- It is periodic at π intervals, which means that the output for a value f will be the same than the output for value f + π (or 2π, 3π, etc.)
