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.
The Math.sinh() static method returns the hyperbolic sine of a number. That is,
Try it
console.log(Math.sinh(0));
// Expected output: 0
console.log(Math.sinh(1));
// Expected output: 1.1752011936438014
console.log(Math.sinh(-1));
// Expected output: -1.1752011936438014
console.log(Math.sinh(2));
// Expected output: 3.626860407847019
Syntax
js
Math.sinh(x)
Parameters
x-
A number.
Return value
The hyperbolic sine of x.
Description
Because sinh() is a static method of Math, you always use it as Math.sinh(), rather than as a method of a Math object you created (Math is not a constructor).
Examples
Using Math.sinh()
js
Math.sinh(-Infinity); // -Infinity
Math.sinh(-0); // -0
Math.sinh(0); // 0
Math.sinh(1); // 1.1752011936438014
Math.sinh(Infinity); // Infinity
