sinh
Computes the hyperbolic sine of the specified argument
#include <math.h>
double sinh (
double x);
The sinh function returns the hyperbolic sine value. When the argument is outside the permissible range, errno is set and matherr is called. Unless the function is replaced, matherr prints a diagnostic message using the stderr stream.
The sinh function computes the hyperbolic sine of x. A range error occurs if the magnitude of x is too large.
#include <math.h> #include <stdio.h> main () { printf ("%f\n", sinh (.5) ); }
produces the following:
