Finally, in order to select, for example, the hyperbolic tangent (tanh)
function, simply press @@TANH@.
NOTE: To see additional options in these soft menus, press the L
key or the „«keystroke sequence.
For example, to calculate tanh(2.5), in the ALG mode, when using SOFT
menus over CHOOSE boxes, follow this procedure:
In RPN mode, the same value is calculated using:
As an exercise of applications of hyperbolic functions, verify the following
SINH (2.5) = 6.05020..
COSH (2.5) = 6.13228..
TANH(2.5) = 0.98661..
EXPM(2.0) = 6.38905....
Operations with units
Numbers in the calculator can have units associated with them. Thus, it is
possible to calculate results involving a consistent system of units and
produce a result with the appropriate combination of units.
The UNITS menu
‚Û(associated with the 6 key).
CHOOSE boxes, the result is the following menu:
„´@@HYP@ @@TANH@ 2.5`
2.5`„´) @ @HYP@ @@TANH@
ASINH(2.0) = 1.4436...
ACOSH (2.0) = 1.3169...
ATANH(0.2) = 0.2027...
