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.

Return value

The hyperbolic cosine of x.

Description

Because cosh() is a static method of Math, you always use it as Math.cosh(), rather than as a method of a Math object you created (Math is not a constructor).

Examples

Using Math.cosh()

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