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
values:
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:
Note: To see additional options in these soft menus, press the L key or the
