tanh function in C Programming language

tanh function in  C programming language

In this tutorial, we will discuss about tanh function in C Programming language

Description

Description of tanh() function in  C programming language

The tanh() function in C programming  language (C library function) returns the hyperbolic tangent value of the radian angle x

tanh() : In the C Programming language, the tanh()  function is used to calculate a hyperbolic tangent value of given arguments.

Declaration of tanh()

The declaration of the tanh() Arithmetic function in the C programming language

double tanh(double x);

Parameter or Arguments list

parameter of tanh() function is:

x- this is a floating point value assigned to angle as the parameter of this function and always measured in radians

Returns

The tanh function returns hyperbolic tangent value of x, measured in radians.

Required header

The required header file for the tanh function in the C programming  language is

#include <math.h>

Example

The following example shows the usage if tanh() function

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    double x=0.5,y=1;

    printf("Hyperbolic tangent value of %f is:%f\n",x,tanh(x));
    printf("Hyperbolic tangent value of %f is:%f\n",y,tanh(y));
    getch();
    return 0;
}

 

When the above program is compiled and run, it will produce the following results.

Hyperbolic Tangent value of 0.500000 is: 0.462117
Hyperbolic Cosine value of 1.000000 is: 0.761594

 

Program 2

#include <stdio.h>
#include <math.h>

int main()
{   //define the variable
    double tanhValue;
    double inputValue;
    //get input from user
    printf("Please enter the value to calculate tanh value :");
    scanf("%lf",&inputValue);
    //calculate the Hyperbolic tangent value
    tanhValue=tanh(inputValue);
    //display the Hyperbolic tangent value
     printf("\nHyperbolic tangent value of %lf is %lf\n",inputValue,tanhValue);
    getch();
    return 0;
}

When the above program is compiled and run, it will produce the following results.

Please enter the value to calculate tanh value :0.5
Hyperbolic tangent value of 0.500000 is 0.462117
