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:
- Example 1:
<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>

0 1.1752011936438014 74.20321057778875 1792456423.065796 -3.626860407847019 27.28991719712775
- 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_rightfilter_noneOutput:
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>
chevron_rightfilter_noneOutput:
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.
- Example 1:
<script>
// Printing hyperbolic sine of some numbers from 0 to 9
// taken as parameter of Math.sinh() function.
for
(i = 0; i < 10; i++) {
document.write(Math.sinh(i) +
"<br>"
);
}
</script>
chevron_rightfilter_noneOutput:
