Math.sinh()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
TheMath.sinh() static method returns the hyperbolic sine of a number. That is,
Try it
console.log(Math.sinh(0));// Expected output: 0console.log(Math.sinh(1));// Expected output: 1.1752011936438014console.log(Math.sinh(-1));// Expected output: -1.1752011936438014console.log(Math.sinh(2));// Expected output: 3.626860407847019Syntax
js
Math.sinh(x)Parameters
xA number.
Return value
The hyperbolic sine ofx.
Description
Becausesinh() is a static method ofMath, you always use it asMath.sinh(), rather than as a method of aMath object you created (Math is not a constructor).
Examples
Using Math.sinh()
