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 ⁨2015年7月⁩.

Math.cosh() は静的メソッドで、数値の双曲線余弦（ハイパーボリックコサイン）を返します。

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

試してみましょう

console.log(Math.cosh(0));
// 予想される結果: 1
console.log(Math.cosh(1));
// 予想される結果: 1.543080634815244 （およそ）
console.log(Math.cosh(-1));
// 予想される結果: 1.543080634815244 （およそ）
console.log(Math.cosh(2));
// 予想される結果: 3.7621956910836314
