Math.cosh()

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.cosh() static method returns the hyperbolic cosine of a number. That is,

𝙼𝚊𝚝𝚑.𝚌𝚘𝚜𝚑 (𝚡) = cosh (x) = \frac{e^{x} + e^{- x}}{2}

Try it

console.log(Math.cosh(0));
// Expected output: 1
console.log(Math.cosh(1));
// Expected output: 1.543080634815244 (approximately)
console.log(Math.cosh(-1));
// Expected output: 1.543080634815244 (approximately)
console.log(Math.cosh(2));
// Expected output: 3.7621956910836314

Syntax

Math.cosh(x)

Parameters

x: A number.

Math.cosh(-Infinity); // Infinity
Math.cosh(-1); // 1.5430806348152437
Math.cosh(-0); // 1
Math.cosh(0); // 1
Math.cosh(1); // 1.5430806348152437
