C++ Math tanh()

Math tanh() Function

In C++, the tanh() function is defined in the <cmath> or <math.h> header file and is used to calculate the hyperbolic tangent of an angle specified in radians. The hyperbolic tangent is mathematically defined using exponential functions and is commonly used in mathematics, physics, engineering, and machine learning applications.

The tanh() function accepts integer, float, double, and long double values as input and returns a value in the range -1 to 1. It is widely used in neural networks, signal processing, and hyperbolic function calculations.

Mathematically,

Syntax

It has the following syntax.

Parameters

x: The value whose hyperbolic tangent is to be computed.

Return value

It returns the hyperbolic tangent of x.

Examples of the List tanh() Function

Here, we are going to discuss several examples to demonstrate the List tanh() Function Function.
