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);

Parameters

• 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
