What is the use of Math.asinh() and Math.acosh() functions in javascript?

Math.asinh() and Math.acosh() functions are used to find the hyperbolic arc-sine and hyperbolic arc-cosine of a number respectively. These functions are static methods of Math, therefore they are always used as Math.asinh() and Math.acosh(), rather than as methods of a math object created.

Math.asinh()

This method is used to find the hyperbolic arc-sine of a number. It takes a number as a parameter and returns hyperbolic sine value.

Example

Live Demo

<html>
<body>
<script>
   document.write(Math.asinh(2));
   document.write("</br>");
   document.write(Math.asinh(7));
</script>
</body>
</html>

Output

1.4436354751788103
2.644120761058629


Math.acosh()

This method is used to find the hyperbolic arc-cosine of a number. It takes a number as a parameter and returns hyperbolic cosine value.

Example

Live Demo

<html>
<body>
<script>
   document.write(Math.acosh(2));
   document.write("</br>");
   document.write(Math.acosh(7));
</script>
</body>
</html>
