Format
#include <math.h> double cosh(double x);
Language Level: ANSI, POSIX, XPG4
cosh calculates the hyperbolic cosine of x. The value x
is expressed in radians.
Return Value
cosh returns the hyperbolic cosine of x. If
the result is too large, cosh returns the value HUGE_VAL and sets
errno to
Example
This example calculates y to be the hyperbolic cosine
of x.
#include <math.h> #include <stdio.h>
int main(void)
{
double x,y;
x = 7.2; y = cosh(x);
printf("cosh( %lf ) = %lf\n", x, y);
/**************************************
The output should be:
cosh( 7.200000 ) = 669.715755 **************************************/ }
