cosh

Name

cosh, coshf, coshl
- hyperbolic cosine function

Library

libm.lib

Synopsis

#include <math.h>

double cosh (double x);

float coshf (float x);

long double cosh (long double x);

Detailed description

The cosh, and coshf functions compute the hyperbolic cosine of x. The function coshl is an alias to the function cosh.

Examples

#include <math.h>
int main( void )
{
   double pi = 3.1415926535;
   double x, y;
   x = pi / 2;
   y = cosh( x );
   printf( "cosh( %f ) = %f\n", x, y );
   y = coshf( x );
   printf( "coshf( %f ) = %f\n",x, y );
   y = coshl( x );
   printf( "coshl( %f ) = %f\n",x, y );
}

Output

cosh( 1.570796 ) = 2.509178
coshf( 1.570796 ) = 2.509178
coshl( 1.570796 ) = 2.509178
