JavaScript | Math.sinh() function

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)

Parameter: This function accepts a single parameter p is a number for which the value of hyperbolic sine is going to be calculated.

Returns: It returns the calculated value of the hyperbolic sine of the number.

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:

  <script>   // Printing hyperbolic sine of some numbers   // taken as parameter of Math.sinh() function.   document.write(Math.sinh(0) + "<br>");   document.write(Math.sinh(1) + "<br>");   document.write(Math.sinh(5) + "<br>");   document.write(Math.sinh(22) + "<br>");   document.write(Math.sinh(-2) + "<br>");   document.write(Math.sinh(4)); </script>

• Example 2: >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.

  <script>   // complex number can not be calculated as    //the hyperbolic sine.   document.write(Math.sinh(1 + 2i)); </script>

  chevron_right

  filter_none

  Output:

  Error: Invalid or unexpected token

• Example 3: 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.

  <script>   // 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.   document.write(Math.sinh("geeksforgeeks") + "<br>");   document.write(Math.sinh("gfg")); </script>

  filter_none

  Output:

  NaN
  NaN

Application: 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.
