cosh in c

What is cosh in c programming?

cosh in c is a mathematical function which is used to calculate hyperbolic cosine of a given number.

This function is defined in math.h header file.

Prototype

double cosh(double y);

Parameters

cosh function takes floating point value as input parameter.

Return value

cosh function returns hyperbolic cosine value of a given number.


Example program for cosh in c

#include<stdio.h>
#include<math.h>
int main()
{
  double m=0.8,res;
  res=cosh(m);
  printf("\n\n\tHyperbolic cosine value is %lf \n",res);
  return 0;
}
Example for cosh in c programming

While using gcc use below command to add math header.

gcc file_name.c -lm

Code explanation

The hyperbolic cosine value of a given number is found by calling cosh function and the result is printed onto the console.
