C Language: cosh function
(Hyperbolic Cosine)
In the C Programming Language, the cosh function returns the hyperbolic cosine of x.
Syntax
The syntax for the cosh function in the C Language is:
double cosh(double x);
Parameters or Arguments
- x
- A value expressed in radians (not degrees).
Returns
The cosh function returns the hyperbolic cosine of x. If the magnitude of x is too large, the cosh function will return a range error.
Required Header
In the C Language, the required header for the cosh function is:
#include <math.h>
Applies To
In the C Language, the cosh function can be used in the following versions:
- ANSI/ISO 9899-1990
cosh Example
/* Example using cosh by TechOnTheNet.com */
#include <stdio.h>
#include <math.h>
int main(int argc, const char * argv[])
{
/* Define temporary variables */
double value;
double result;
/* Assign the value we will find the cosh of */
value = 0.5;
/* Calculate the Hyperbolic Cosine of value */
result = cosh(value);
/* Display the result of the calculation */
printf("The Hyperbolic Cosine of %f is %f\n", value, result);
return 0;
}
When compiled and run, this application will output:
The Hyperbolic Cosine of 0.500000 is 1.127626
