Math.asinh()

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.asinh() static method returns the inverse hyperbolic sine of a number. That is,

\begin{aligned} 𝙼𝚊𝚝𝚑.𝚊𝚜𝚒𝚗𝚑 (𝚡) & = arsinh (x) = the unique y such that sinh (y) = x \\ = ln (x + \sqrt{x^{2} + 1}) \end{aligned}

Try it

console.log(Math.asinh(1));
// Expected output: 0.881373587019543
console.log(Math.asinh(0));
// Expected output: 0
console.log(Math.asinh(-1));
// Expected output: -0.881373587019543
console.log(Math.asinh(2));
// Expected output: 1.4436354751788103

Syntax

Math.asinh(x)

Parameters

x: A number.

Math.asinh(-Infinity); // -Infinity
Math.asinh(-1); // -0.881373587019543
Math.asinh(-0); // -0
Math.asinh(0); // 0
Math.asinh(1); // 0.881373587019543
Math.asinh(Infinity); // Infinity
