JavaScript | Math.tanh() Method

Math.tanh() is a function in math library of JavaScript that is used to find the value of hyperbolic tangent of a number.

Calculation of mathematical Formula:

    tanh(p) = sin(p) / cos(p) = ep - e-p / ep + e-p

Where e is the mathematical constant with value 2.718

Syntax:

    Math.tanh(p);

Parameter(s):

  • p – It represents the value whose hyperbolic tangent value to be found.

Return value:

The return type of this method is number, it returns the hyperbolic tangent value of the given p.

Example 1: Find the tanh of numeric values

console.log(Math.tanh(0));
console.log(Math.tanh(7));
console.log(Math.tanh(-5));
console.log(Math.tanh(4.52));

Output

0
0.9999983369439447
-0.9999092042625951
0.9997628864418443

Example 2: Find the tanh of non-numeric values

console.log(Math.tanh("IncludeHelp"));
// Output: NaN

console.log(Math.tanh(3 + 5i));
// Output: Uncaught SyntaxError: Invalid or unexpected token
