JavaScript Math tanh() Method
Last Updated :
23 May, 2023
Javascript Math.tanh() method is used to calculate the value of the hyperbolic tangent of a number.
Syntax:
Math.tanh(x)
Parameter: This method accepts a single parameter as mentioned above and described below:
- x: which is a number for which the value of hyperbolic tangent is going to be calculated.
Return value: It returns the calculated value of the hyperbolic tangent of the number.< Below example illustrate the Math.tanh() method in JavaScript:
Example: Here formula for calculating the hyperbolic tangent of any number e is a mathematical constant having an approximate value equal to 2.718.
Input :Math.tanh(0)
Output : 0
Example: In the same way hyperbolic tangent of any number can be calculated just after replacing p with the desired number. Here the same as the above calculation, when we put 18 instead of x then the value becomes as output shown above.
Input : Math.tanh(18)
Output : 0.9999999999999996
Example: Below is an example of the Math.tanh() Method.
javascript
console.log(Math.tanh(0));
console.log(Math.tanh(1));
console.log(Math.tanh(5));
console.log(Math.tanh(22));
console.log(Math.tanh(-2));
console.log(Math.tanh(4));
|
Output:
0
0.7615941559557649
0.9999092042625951
1
-0.9640275800758169
0.999329299739067
Example: It is an error case because the complex number can not be taken as the parameter of the function only integer value can be taken as the parameter.
javascript
console.log(Math.tanh(1 + 2i));
|
Output:
Error: Invalid or unexpected token
Example: Other than integer nothing is accepted as the parameter of the function which is why here string as the parameter gives NaN i.e, not a number.
javascript
console.log(Math.tanh( "geeksforgeeks" ));
console.log(Math.tanh( "gfg" ));
|
Output:
NaN
NaN
Example: Its practical application is that whenever we need to find the value of the hyperbolic tangent of a number that time we take the help of Math.tanh() function in JavaScript.
javascript
for (i = 0; i < 10; i++) {
console.log(Math.tanh(i));
}
|
Output:
0
