sinh(3m)
NAME
sinh, cosh, tanh − hyperbolic functions
SYNTAX
#include <math.h>
double sinh(x)
double x;
double cosh(x)
double x;
double tanh(x)
double x;
DESCRIPTION
These functions compute the designated hyperbolic functions for real arguments.
DIAGNOSTICS
Both sinh and cosh return HUGE (and sinh may return -HUGE for negative x ) when the correct value would overflow and set errno to ERANGE.
These error-handling procedures may be changed with the function matherr(3m).
