HP 50g manual Operations with units, Units menu

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:

„´@@HYP@ @@TANH@ 2.5`

In RPN mode, the same value is calculated using:

2.5`„´)@@HYP@ @@TANH@

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….

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

The units menu is launched by the keystroke combination ‚Û(associated with the 6 key). With system flag 117 set to CHOOSE boxes, the result is the following menu:
