COSH
COTH
SINH
TANH

Syntax: COSH (x)
   and: COTH (x)
   and: SINH (x)
   and: TANH (x)
Location: Hyper, Hyperbola

These functions all return hyperbolic mathematical functions:

COSH is defined as:  ( EXP(x) + EXP(-x) ) / 2
COTH is defined as:  1/TANH(x)
SINH is defined as:  ( EXP(x) - EXP(-x) ) / 2
TANH is defined as:  SINH(x) / COSH(x)

CROSS-REFERENCE:
ARCOSH is the inverse function of COSH.
