# Math.sinh()

Math.sinh() 함수(쌍곡선 함수)는 사인값을 반환합니다 이 값은 아래와같은 식을통해서 표현할 수 있습니다.constant e:

$Math.sinh(x)=ex-e-x2\mathtt{\operatorname{Math.sinh(x)}} = \frac{e^x - e^{-x}}{2}$

## Syntax

Math.sinh(x)

### Parameters

x
숫자.

사인값.

## Description

sinh() 는 Math 의 정적 함수이기 때문에, 자바스크립트 어디든 Math.sinh() 를 사용할 수 있습니다, 따라서  Math 오브젝트를 생성해서는 안됩니다. (Math 는 constructor(생성자) 가 아닙니다.).

## Examples

### Math.sinh() 사용하기

Math.sinh(0); // 0
Math.sinh(1); // 1.1752011936438014


## Polyfill

This can be emulated with the help of the Math.exp() function:

Math.sinh = Math.sinh || function(x) {
return (Math.exp(x) - Math.exp(-x)) / 2;
}


or using only one call to the Math.exp() function:

Math.sinh = Math.sinh || function(x) {
var y = Math.exp(x);
return (y - 1 / y) / 2;
}
