JavaScript Math sinh() Method

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.

// 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));

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. 

// 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. 

// 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"));

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.

// 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));
}
