cosh() - math.h

The C library function double cosh(double x) returns the hypebolic cosine of x.

Syntax

double cosh(double x)	

Example

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

int main ()
{
   double x;

   x = 0.5;
   printf("The hyperbolic cosine of %lf is %lf\n", x, cosh(x));

   x = 1.0;
   printf("The hyperbolic cosine of %lf is %lf\n", x, cosh(x));

   x = 1.5;
   printf("The hyperbolic cosine of %lf is %lf\n", x, cosh(x));

   return(0);
}
