Hyperbolic {base}R Documentation

Hyperbolic Functions

Description

These functions give the obvious hyperbolic functions. They respectively compute the hyperbolic cosine, sine, tangent, and their inverses, arc-cosine, arc-sine, arc-tangent (or “area cosine”, etc).

Usage

cosh(x)
sinh(x)
tanh(x)
acosh(x)
asinh(x)
atanh(x)

Arguments

x a numeric vector

Details

These are generic functions: methods can be defined for them individually or via the Math group generic.

The logistic distribution function plogis is a shifted version of tanh().
