C++ Math tanh()

The function computes the hyperbolic tangent of an angle given in radian.

Mathematically,

tanhx = e^x -e^-x/ e^x+e^-x

Syntax

Suppose the angle is 'x':

float tanh(float x);
double tanh(double x);
long double tanh(long double x);
double tanh(integral x);

Parameter

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

Return value

It returns the hyperbolic tangent of x.

Example 1

Let's see the simple example when the value of x is integer type.

#include 
#include
using namespace std;
 int main()
{
    int degree =60;
    float x = degree*3.14/180;
    std::cout << "Value of degree is : " <

Output:

Value of degree is : 60
tanh(x) : 0.780507

In this example, tanh(x) function computes the hyperbolic tangent of x and returns the value 0.78.

Example 2

Let's see the simple example when the value of x is float type.

#include 
#include
using namespace std;
int main()
{
    float degree = 45.2;
    float x = degree*3.14/180;
    std::cout << "Value of degree is : " <

Output:

Value of degree is : 45.2
tanh(x) : 0.657552

In this example, tanh(x) function computes the hyperbolic tangent of x and returns the value 0.65.
