JavaScript Math atanh() Method (original) (raw)

Last Updated : 12 Jul, 2024

The Javascript **Math.atanh() method is used to return the hyperbolic arctangent of a number. The atanh() is a static method of Math, therefore it is always used as Math.atanh(), rather than as a method of a Math object created.

Math.atanh (x) = arctanh(x) = y such that tanh (y) = x

**Syntax:

Math.atanh(value)

**Parameters: This method accepts a single parameter as mentioned above and described below:

**Returns: It returns the hyperbolic arc-tangent of the given number.

Below are examples of the **Math.atanh() Method.

**Example 1: This example shows the hyperbolic arctangent when 1 is passed as a parameter.

JavaScript `

console.log("When 1 is passed as a parameter: " + Math.atanh(1));

`

Output

When 1 is passed as a parameter: Infinity

**Example 2: This example shows the hyperbolic arctangent when 0 is passed as a parameter.

JavaScript `

console.log("When 0 is passed as a parameter: " + Math.atanh(0));

`

Output

When 0 is passed as a parameter: 0

**Example 3: This example shows the hyperbolic arctangent when 2 is passed as a parameter.

JavaScript `

console.log("When 2 is passed as a parameter: " + Math.atanh(2));

`

Output

When 2 is passed as a parameter: NaN

**Example 4: This example shows the hyperbolic arctangent when 0.5 is passed as a parameter.

JavaScript `

console.log("When 0.5 is passed as a parameter: " + Math.atanh(0.5));

`

Output

When 0.5 is passed as a parameter: 0.5493061443340548
