Aplets are stored in the Aplet library. See “Aplet library” on page 1-16for 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 1-18for further information.

Aplet

Use this aplet to explore:

name

 

 

 

Function

Real-valued, rectangular functions y in

 

terms of x. Example: y = 2x2 + 3x + 5 .

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 θ.

 

Example: r = 2 cos (4θ) .

Sequence

Sequence functions U in terms of n, or

 

in terms of previous terms in the same or

 

another sequence, such as Un – 1 and

 

Un – 2 . Example: U1 = 0 , U2 = 1

 

and Un = Un – 2 + Un – 1 .

Solve

Equations in one or more real-valued

 

variables. Example: x + 1 = x2 – x – 2 .

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.
