The JavaScript Math.sinh() is an inbuilt method in JavaScript that is used to calculate the value of the hyperbolic sine of a number.
Syntax:
Math.sinh(p)
Examples:
Input : Math.sinh(0)
Output : 0
Explanation: Here formula for calculating the hyperbolic sine of any number is: The number e is a mathematical constant having an approximate value equal to 2.718.
[Tex]= e^0-e^-^0/2
[/Tex]
[Tex]= 0
[/Tex]
[Tex]= e^0-e^-^0/2 
[Tex]= 0 In the same way, the hyperbolic sine of any number can be calculated just after replacing p with the desired number.
Input : Math.sinh(15)
Output : 1634508.6862359024
Explanation: Here same as the above calculation, when we put 15 instead of p then the value becomes as output shown above. Let’s see some JavaScript code:
Example 1: In this example, we will calculate the hyperbolic sine of some numbers using the sinh() method.
javascript
// Printing hyperbolic sine of some numbers// taken as parameter of Math.sinh() method.console.log(Math.sinh(0));console.log(Math.sinh(1));console.log(Math.sinh(5));console.log(Math.sinh(22));console.log(Math.sinh(-2));console.log(Math.sinh(4)); |
0 1.1752011936438014 74.20321057778875 1792456423.065796 -3.626860407847019 27.28991719712775
Example 2: It is an error case because the complex numbers can not be taken as the parameter of the method only integer value can be taken as the parameter.
javascript
// complex number can not be calculated as// the hyperbolic sine.console.log(Math.sinh(1 + 2i)); |
Output:
Error: Invalid or unexpected token
Example 3: Other than integer nothing is accepted as the parameter of the method which is why here string as the parameter gives NaN i.e., not a number.
javascript
// Any string value as the parameter of the method// gives NaN i.e, not a number// because only number can be used as the parameters.console.log(Math.sinh("neveropen"));console.log(Math.sinh("gfg")); |
NaN NaN
Application:
Its practical application is that whenever we need to find the value of the hyperbolic sine of a number that time we take the help of the Math.sinh() method in JavaScript.
Example 1: This example demonstrates the above-explained approach.
javascript
// Printing hyperbolic sine of some numbers from 0 to 9// taken as parameter of Math.sinh() method.for (i = 0; i < 10; i++) { console.log(Math.sinh(i));} |
