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.
