SINH(S)                  XENIX System V                   SINH(S)



     Name
          sinh, cosh, tanh - Performs 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
          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 can be changed with the
          matherr(S) function.

     Notes
          These routines must be linked by using the -lm linker
          option.
