To find the hyperbolic arctangent of a number, we can use the JavaScript atanh() function from the math module.

Math.atanh(x)

In JavaScript, we can easily use trigonometric functions with the Python math module. The JavaScript math module allows us to perform trigonometry easily and in addition to regular trigonometry, we have access to the hyperbolic trigonometry functions.

With the JavaScript math module, we can find the hyperbolic arctangent of a number easily.

To find the hyperbolic arctangent of a number, we can use the JavaScript atanh() function from the math module.

Below is the JavaScript syntax to find the hyperbolic arctangent of a number.

Math.atanh(x)

The input to the atanh() function must be a numeric value between -1 and 1. The return value will be a numeric value.

console.log(Math.atanh(0.5))
console.log(Math.atanh(0))
console.log(Math.atanh(-0.75))

// Output: 
0.5493061443340549
0.0
-0.9729550745276566

Finding the Inverse Hyperbolic Tangent of a Number in JavaScript

The JavaScript math module also provides us trigonometric functions to find the inverses of the common trigonometric functions. The atanh() function allows us to find the inverse of the hyperbolic tangent of a number.

Below, we show that if we pass a number to tanh() and then call the JavaScript atanh() function, we get back the same number.

console.log(Math.atanh(Math.tanh(10)))

// Output: 
10.0

Hopefully this article has been beneficial for you to understand how to use the math atanh() function in JavaScript to find the hyperbolic arctangent of a number.
