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
- When 1 is passed as a parameter.
<
script
type
=
"text/javascript"
>
document.write("OUTPUT : " + Math.atanh(1));
</
script
>
OUTPUT:
OUTPUT : Infinity
- When 0 is passed as a parameter.
<
script
type
=
"text/javascript"
>
document.write("OUTPUT : " + Math.atanh(0));
</
script
>
OUTPUT:
OUTPUT : 0
- When 2 is passed as a parameter.
<
script
type
=
"text/javascript"
>
document.write("OUTPUT : " + Math.atanh(2));
</
script
>
OUTPUT:
OUTPUT : NaN
- When 0.5 is passed as a parameter.
<
script
type
=
"text/javascript"
>
document.write("OUTPUT : " + Math.atanh(0.5));
</
script
>
OUTPUT:
OUTPUT : 0.5493061443340548
