Compatibility:This function is compatible with the following targets:
|
|
double cosh(double x);
float coshf(float);
long double coshl(long double);Parameters:
Parameters for this function are:
cosh() returns the hyperbolic cosine of x.
#include <math.h>
#include <stdio.h>
int main(void)
{
double x = 0.0;
printf("Hyperbolic cosine of %f is %f.\n",x,cosh(x));
return 0;
}
Output:
Hyperbolic cosine of 0.000000 is 1.000000.
