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:
- value: This parameter holds the number whose hyperbolic arc-tangent you want to know.
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)); |
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)); |
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)); |
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)); |
When 0.5 is passed as a parameter: 0.5493061443340548
