JavaScript - Math.acosh() Method
The JavaScript Math.acosh() method returns inverse hyperbolic cosine of a value. The inverse hyperbolic cosine of x is defined as:
Syntax
Math.acosh(x)
Parameters
x |
Specify the value equal to or greater than 1. |
Return Value
Returns the inverse hyperbolic cosine of a value.
If the x is less than 1, it returns NaN.
Example:
In the example below, Math.acosh() method is used to find out the inverse hyperbolic cosine of a value.
var txt; txt = "Math.acosh(0) = " + Math.acosh(0) + "<br>"; txt = txt + "Math.acosh(2) = " + Math.acosh(2) + "<br>"; txt = txt + "Math.acosh(4) = " + Math.acosh(4) + "<br>";
The output (value of txt) after running above script will be:
Math.acosh(0) = NaN Math.acosh(2) = 1.3169578969248166 Math.acosh(4) = 2.0634370688955608
