NAME

6       sinh, cosh, tanh - hyperbolic functions
7

SYNOPSIS

9       #include <math.h>
10
11       double sinh(x)
12       double x;
13
14       double cosh(x)
15       double x;
16
17       double tanh(x)
18       double x;
19

DESCRIPTION

21       These  functions  compute  the designated hyperbolic functions for real
22       arguments.
23

ERROR (due to Roundoff etc.)

25       Below 2.4 ulps; an ulp is one Unit in the Last Place.
26

DIAGNOSTICS

28       Sinh and cosh return the reserved operand on a VAX if the correct value
29       would overflow.
