Aplets are stored in the Aplet
library. See "Aplet library"
on page 1-16 for further
information.
You can modify
configuration settings for the graphical, tabular, and
symbolic views of the aplets in the following table. See
"Aplet view configuration" on page 1-18 for further
information.
Aplet Use this aplet to explore:
name
Function Real-valued, rectangular functions y in
terms of x. Example:
Inference Confidence intervals and Hypothesis
tests based on the Normal and
Students-t distributions.
Parametric Parametric relations x and y in terms of
t. Example: x = cos(t) and y = sin(t).
Polar Polar functions r in terms of an angle .
Example:
Sequence Sequence functions U in terms of n, or
in terms of previous terms in the same or
another sequence, such as
U
n 2
and
Solve Equations in one or more real-valued
variables. Example:
Statistics One-variable (x) or two-variable (x and
y) statistical data.
In addition to these aplets, which can be used in a variety
of applications, the hp 39g+ is supplied with two
teaching aplets: Quad Explorer and Trig Explorer. You
cannot modify configuration settings for these aplets.
