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.

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.

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 HOME too.

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.

The

SYMB

PLOT

and

NUM

keys

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.
