Math.sinh() is an inbuilt function in JavaScript which is used to calculate the value of hyperbolic sine of a number.
Syntax:
Math.sinh(p)
- Here the parameter p is a number for which the value of hyperbolic sine is going to be calculated.
- It returns the calculated value of the hyperbolic sine of the number.
Parameter:
Return value:
Examples:
Input: Math.sinh(0)
Output: 0
Explanation:
Here formula for calculating hyperbolic sine of any number is : The number e is a mathematical constant having an approximate value equal to 2.718.
In the same way 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 above calculation, when we put 15 instead of p then the value becomes as output shown above.
Let’s see some JavaScript code:
// Printing hyperbolic sine of some numbers // taken as paramter of Math.sinh() function. 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)); |
Output:
> 0 > 1.1752011936438014 > 74.20321057778875 > 1792456423.065796 > -3.626860407847019 > 27.28991719712775
- It is an error case because complex number can not be taken as the parameter of the function 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
- Other than integer nothing is accepted as the parameter of the function that is why here string as the parameter gives NaN i.e, not a number.
// Any string value as the parameter of the function
// 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"
));
Output:
> NaN > NaN
Errors and Exceptions:
- Its practical application is that whenever we need to find the value of hyperbolic sine of a number that time we take the help of Math.sinh() function in JavaScript.
Application:
// Printing hyperbolic sine of some numbers from 0 to 9 // taken as paramter of Math.sinh() function. for (i = 0; i < 10; i++) { console.log(Math.sinh(i)); + "<br>" ; } |
Output:
> 0 > 1.1752011936438014 > 3.626860407847019 > 10.017874927409903 > 27.28991719712775 > 74.20321057778875 > 201.71315737027922 > 548.3161232732465 > 1490.4788257895502 > 4051.54190208279
