public static float Tan(float f)

Parameters

f

float
The input angle, in radians.

Returns

Type

Description

floatThe return value in the range (-Infinity, Infinity).

Remarks

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.)

Examples

using UnityEngine;using System.Collections;public class ExampleClass : MonoBehaviour{    void Example()    {        // Prints 2.287733E+07        Debug.Log(Mathf.Tan(-Mathf.PI / 2.0f));        // Prints 0        Debug.Log(Mathf.Tan(0.0f));        // Prints 2.287733E+07        Debug.Log(Mathf.Tan(Mathf.PI / 2.0f));        // Prints 1                Debug.Log(Mathf.Tan(Mathf.PI / 4.0f));        // Prints 1        Debug.Log(Mathf.Tan(Mathf.PI + Mathf.PI / 4.0f));    }}
