Chapter 10 - Transcendental Functions

Hyperbolic Functions

MathLib provides hyperbolic and inverse hyperbolic functions.

$cosh(x)$	Hyperbolic cosine of x.
$sinh(x)$	Hyperbolic sine of x.
$tanh(x)$	Hyperbolic tangent of x.
$acosh(x)$	Inverse hyperbolic cosine of x.
$asinh(x)$	Inverse hyperbolic sine of x.
$atanh(x)$	Inverse hyperbolic tangent of x.

These functions are based on other transcendental functions and defer most exception generation to the core functions they use.
