JavaScript Math.atanh( )

The Math.atanh() function in JavaScript is used to return the hyperbolic arctangent of a number.
Math.atanh (x) = arctanh(x) = y such that tanh (y) = x
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.

Syntax:

Math.atanh(value)

Parameters Used:
1. value: It is the number whose hyperbolic arc-tangent you want to know.

Return Value:
It returns the hyperbolic arc-tangent of the given number.

Examples:

Input : Math.atanh(1)
Output : Infinity

Input : Math.atanh(0)
Output : 0

Input : Math.atanh(2)
Output : NaN

Input : Math.atanh(0.5)
Output : 0.5493061443340548

1. When 1 is passed as a parameter.

   <script type="text/javascript">    document.write("OUTPUT : " + Math.atanh(1)); </script>

   OUTPUT:

   OUTPUT : Infinity

2. When 0 is passed as a parameter.

   <script type="text/javascript">    document.write("OUTPUT : " + Math.atanh(0)); </script>

   OUTPUT:

   OUTPUT : 0

3. When 2 is passed as a parameter.

   <script type="text/javascript">    document.write("OUTPUT : " + Math.atanh(2)); </script>

   OUTPUT:

   OUTPUT : NaN

4. When 0.5 is passed as a parameter.

   <script type="text/javascript">    document.write("OUTPUT : " + Math.atanh(0.5)); </script>

   OUTPUT:

   OUTPUT : 0.5493061443340548
