JavaScript - Math.tanh() Method
The JavaScript Math.tanh() method returns hyperbolic tangent of a value. The hyperbolic tangent of x is defined as:
where e is an Euler's number.
Syntax
Math.tanh(x)
Parameters
x |
Specify the value. |
Return Value
Returns the hyperbolic tangent of a value.
Example:
In the example below, Math.tanh() method is used to find out the hyperbolic tangent of a value.
var txt; txt = "Math.tanh(0) = " + Math.tanh(0) + "<br>"; txt = txt + "Math.tanh(2) = " + Math.tanh(2) + "<br>"; txt = txt + "Math.tanh(4) = " + Math.tanh(4) + "<br>"; txt = txt + "Math.tanh(-2) = " + Math.tanh(-2) + "<br>"; txt = txt + "Math.tanh(-4) = " + Math.tanh(-4) + "<br>";
The output (value of txt) after running above script will be:
Math.tanh(0) = 0 Math.tanh(2) = 0.9640275800758169 Math.tanh(4) = 0.999329299739067 Math.tanh(-2) = -0.9640275800758169 Math.tanh(-4) = -0.999329299739067
