In this tutorial, we will discuss about tanh function in C Programming language
Description of tanh() in C programming language
The tanh() function in C programming language (C library) returns the hyperbolic tangent value of the radian angle x
tanh() : In the C Programming language, this is used to calculate a hyperbolic tangent value of given arguments.
The declaration of the tanh() in the C programming language
double tanh(double x);
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
This returns hyperbolic tangent value of x, measured in radians.
The required header file for this function in the C programming language is
#include <math.h>
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
