| Hyperbolic {base} | R Documentation |
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).

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

acos, asin, atan.
The logistic distribution function plogis is a shifted
version of tanh().
