STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       cosh():	XPG4

       sinh():	XPG4

       tanh():	XPG4

DESCRIPTION

       The sinh(), sinhf(), and sinhl() functions compute the hyperbolic sine of x.  Both sinh(x), sinhf(x), and sinhl(x) are defined as (exp(x) -
       exp(-x))/2.

       The  cosh(), coshf(),  and coshl() functions compute the hyperbolic cosine of x.  Both cosh(x), coshf(x), and coshl(x) are defined as (e**x
       + e**(-x))/2.

       The tanh(), tanhf(), and tanhl() functions compute the hyperbolic tangent of x.	Both tanh(x), tanhf(x), and tanhl(x) are defined as  (e**x
       - e**(-x))/(e**x + e**(-x)).
