`{ COSH | SINH | TANH | ACOSH | ASINH | ATANH } (arg)`

## Syntax Elements

arg
Any real number.
Function Result
COSH(arg) Hyperbolic cosine of arg.
SINH(arg) Hyperbolic sine of arg.
TANH(arg) Hyperbolic tangent of arg.
ACOSH(arg) Inverse hyperbolic cosine of arg. The inverse hyperbolic cosine is the value whose hyperbolic cosine is a number so that:

acosh(cosh(arg)) = arg

ASINH(arg) Inverse hyperbolic sine of arg. The inverse hyperbolic sine is the value whose hyperbolic sine is a number so that:

asinh(sinh(arg)) = arg

ATANH(arg) Inverse hyperbolic tangent of arg. The inverse hyperbolic tangent is the value whose hyperbolic tangent is a number so that:

atanh(tanh(arg)) = arg
