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: 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.
