TANH function

Description

Hyperbolic tangent function. TANH(x) returns the hyperbolic tangent of the angle x. The argument x must be expressed in radians. To convert degrees to radians you use the RADIANS function.

The hyperbolic tangent can be defined as: $$ \operatorname{tanh}(x) = \frac{\operatorname{sinh}(x)}{\operatorname{cosh}(x)} $$ where sinh is the hyperbolic sine function and cosh is the hyperbolic cosine function.
