Hyperbolic functions and their inverses

Selecting Option 4. HYPERBOLIC.. , in the MTH menu, and pressing @@OK@@,
produces the hyperbolic function menu:
The hyperbolic functions are:
Hyperbolic sine, SINH, and its inverse, ASINH or sinh
Hyperbolic cosine, COSH, and its inverse, ACOSH or cosh
Hyperbolic tangent, TANH, and its inverse, ATANH or tanh
This menu contains also the functions:
Finally, option 9. MATH, returns the user to the MTH menu.
For example, in ALG mode, the keystroke sequence to calculate, say, tanh(2.5),
is the following:
„´
4 @@OK@@
5 @@OK@@
2.5`
The screen shows the following output:
In the RPN mode, the keystrokes to perform this calculation are the following:

EXPM(x) = exp(x) – 1,
LNP1(x) = ln(x+1).
