For example, to calculate tanh(2.5), in the ALG mode, when using SOFT

menus over CHOOSE boxes, follow this procedure:

„´ Select MTH menu

)@@HYP@ Select the HYPERBOLIC.. menu

@@TANH@ Select the TANH function

2.5` Evaluate tanh(2.5)

In RPN mode, the same value is calculated using:

2.5` Enter argument in the stack

„´ Select MTH menu

)@@HYP@ Select the HYPERBOLIC.. menu

@@TANH@ Select the TANH function

As an exercise of applications of hyperbolic functions, verify the following

SINH (2.5) = 6.05020.. ASINH(2.0) = 1.4436…

COSH (2.5) = 6.13228.. ACOSH (2.0) = 1.3169…

TANH(2.5) = 0.98661.. ATANH(0.2) = 0.2027…

EXPM(2.0) = 6.38905…. LNP1(1.0) = 0.69314….

Once again, the general procedure shown in this section can be applied for

selecting options in any calculator menu.

Real number functions

Selecting option 5. REAL.. in the MTH menu, with system flag 117 set to

CHOOSE boxes, generates the following menu list:
