JavaScript Math sinh() Method
Last Updated : 12 Jul, 2024
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.
e^p-e^-^p/2 = e^0-e^-^0/2 = 1-1/2 = 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));
Output0 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("geeksforgeeks")); console.log(Math.sinh("gfg")); 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)); } Output0 1.1752011936438014 3.626860407847019 10.017874927409903 27.28991719712775 74.20321057778875 201.71315737027922 548.3161232732465 1490.4788257895502 4051.54190208279
