The Math.cosh()
static method returns the hyperbolic cosine of a number. That is,
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 Parameters Return value
The hyperbolic cosine of x
.
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).
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
