ACOSH
Prefix/:. Inverse hyperbolic cosine:
cosh~'- X.
I H r-4
TANH
Prefix. Hyperbolic tangent:
sinh .'c/cosh I.
M T' p i-j
ATANH
Prefix. Inverse hyperbolic tangent:
sinh^^(,r/\/]0- ;r-).
EXPM
Prefix, e'" — 1. Argument x is in level 1.
(EXPM is more accurate than EXP
when the argument to e'’’ is close to 0.)
LNPl
Prefix. In (;r -f 1). Argument x is in
level E (LNPl, In plus 1, is more
accurate than LN when the argument to
In is close to 1.)
