The JavaScript Math.acosh() returns the hyperbolic arccosine of a number.
Syntax:
Math.acosh(number)Example:
<!DOCTYPE html>
<html>
<body>
<button onclick="acoshExample()">Try it</button>
<p id="ex-1"></p>
<script>
function acoshExample() {
document.getElementById("ex-1").innerHTML = Math.acosh(2);
}
</script>
</body>
</html>Output:
Click the button to display the hyperbolic arccosine of 2
If the number is less than 1, the method will return NaN:
<!DOCTYPE html>
<html>
<body>
<button onclick="acoshNan)">Try it</button>
<p id="ex-2"></p>
<script>
function acoshNan() {
document.getElementById("ex-2").innerHTML = Math.acosh(0.7);
}
</script>
</body>
</html>
Output:
Click the button to display the hyperbolic arccosine of 0.7
