SINH(3M)                COMMAND REFERENCE                SINH(3M)



NAME
     sinh, cosh, tanh - hyperbolic functions

SYNOPSIS
     #include <math.h>

     double sinh (x)

     double cosh (x)
     double x;

     double tanh (x)
     double x;

DESCRIPTION
     The functions sinh, cosh, and tanh compute the designated
     hyperbolic functions for real arguments.

FILES
     /usr/lib/libm.a
                    Mathematical library functions.

DIAGNOSTICS
     Sinh and cosh are undefined when the correct value would
     overflow; errno is set to ERANGE.
