The tanh method in JavaScript computes the hyperbolic tangent of a specified number.
Syntax
The syntax for the tanh function is expressed as follows:
Example
The tanh() method is represented by the following syntax:
Parameter
num - A number.
Return
The hyperbolic tangent of a number.
JavaScript Math tanh method example
In this section, we will explore the tanh function by examining several examples.
Example 1
Let's see a simple example of tanh method.
Example
<script>
document.writeln(Math.tanh(-1)+"<br>");
document.writeln(Math.tanh(0)+"<br>");
document.writeln(Math.tanh(0.5)+"<br>");
document.writeln(Math.tanh(2));
</script>
Output:
Output
-0.7615941559557649
0
0.46211715726000974
0.9640275800758169
Example 2
In this section, you have the opportunity to evaluate the tanh function using your own custom test cases.
Example
<script>
function display()
{
var x=document.getElementById("num").value;
document.getElementById("result").innerHTML=Math.tanh(x);
}
</script>
<form>
Enter a number: <input type="text" id="num">
<input type="button" onclick="display()" value="submit">
</form>
<p><span id="result"></span></p>
