Special functions, output-control functions, and logic operators and functions
are typically used to control the GLX’s digital and audio output. See “Output-
control Calculations” on page 50 for detailed explanations of these functions
and operators.
Inserting a Function
When you select an item from one of the Functions
menus, it is inserted at the cursor location.
If the item includes a pair of paren-
theses, the cursor will be positioned between them.
Degrees/Radians
A calculation containing a trigonometric function can be set
to operate in degrees or radians. This setting is applied to each calculation sepa-
rately. The lower right corner of the Calculator indicates whether the calculation
that the cursor is on is set for degrees or radians.
To switch the setting, press
to open the Edit menu and select (or deselect)
Radians. After you have switched the setting for a calculation, you must press
or
to make the GLX reevaluate the calculation.
Predefined Constants
The symbol
π
is a predefined constant. The Calculator
will recognize its value as 3.141592 when it is used as part of an expression or on
the right side of an equation.
The symbol e is a predefined constant equal to 2.718282. The capital letter E can
be used interchangeably with e. Typically e is used with the exponent operator (^)
to form e^, the exponential function.
F2 [Data]
Press
(or click [Data]) to select a data source to insert into an equation. See
“Sensor-based Calculations” on page 45 for more information.
The [Data] menu contains sensor measurements, manually entered data, calcula-
tions, and time.
F3 Graph
Press
or (click Graph) to plot the equation that the cursor is on in the pre-
view graph on the lower half of the screen. See “Graphing Equations” on page 44
for more information.

When using the constant
e
, be careful
not to enter it in a way that the GLX will
mistake for scientific notation. See
page 91 for more information.
