The Symb, Plot And Num Keys - HP 39g Master Manual

The hp 39g+ comes with ten standard aplets -
Finance, Function, Inference, Parametric,
Polar, Quadratic Explorer, Sequence, Solve,
Statistics and Trig Explorer. Which one you
want to work with is chosen via the APLET key.
See page 35 for more details on this.
In addition to the standard ten, covered in great detail in the chapters
following, many more aplets are available from the Internet written by other
programmers. Once these are downloaded into your calculator they can also
be accessed via the APLET key. For more detail on this type of aplet, see
the brief summary later in this section, and the chapter entitled "Programming
the hp 39g+" on page 212.
SYMB PLOT
The , and
The SYMB, PLOT and NUM keys are used within aplets to
move from view to view. In most aplets the PLOT view
shows the graph, the SYMB view shows the equations and
the NUM view shows the equations in tabular (numeric)
format.
The VIEWS key pops up a menu from which you can
choose various options. Part of the VIEWS menu for
the Function aplet is shown right. See page 92 for
more information.
The APLET key is used to choose between the
various different aplets available. Everything in the
calculator revolves around aplets, which you can
think of either as miniature programs or as
environments within
which you can work.
Calculator Tip
The name of the active aplet is shown at the top of the
screen, as above. It is important to bear this in mind
because the angle and numeric settings are tied to the
active aplet. Changing aplets may therefore cause these
settings to change in
NUM
keys
too.
