Inverse Hyperbolic Functions
• asinh(z),
acosh(z),
atanh(z),
acsch(z),
asech(z),
acoth(z)—Return the inverse hyperbolic sine, cosine, tangent, cosecant, secant, and cotangent of
z respectively. The returned value is the angle whose
sinh, cosh, tanh, etc, is
z. It is taken from the principal branch of these functions.
Inverse hyperbolic functions are sensitive to roundoff errors from very large arguments and singularities.
Arguments
• z is a dimensionless scalar or a vector of scalars.
