C cosh() function

C cosh() function - Calculate Hyperbolic Cosine

Syntax:

double cosh(double x)

The cosh() function is used to calculate the hyperbolic cosine of x. The value x is expressed in radians.

Parameters:

Return value from cosh()

• Returns the hyperbolic cosine of x.

Example: cosh() function

The following example shows the usage of cosh() function:

#include <math.h>
#include <stdio.h>
 
int main(void)
{
   double x, y;
 
   x = 0;
   y = cosh(x);
   printf("cosh( %lf ) = %lf\n", x, y);
   x = 1;
   y = cosh(x);
   printf("\ncosh( %lf ) = %lf\n", x, y);
   x = 7.3;
   y = cosh(x);
   printf("\ncosh( %lf ) = %lf\n", x, y);
}

Output:

cosh( 0.000000 ) = 1.000000

cosh( 1.000000 ) = 1.543081

cosh( 7.300000 ) = 740.150302
