A set of “aplets” is provided in the APLET view on the hp 39g+. This

effectively mean that it is not just one calculator but nine (or more), changing

capabilities according to which aplet is chosen.

The best way to think of these aplets is as “environments” or “rooms” within

which you can work. Although these environments may seem dissimilar at

first, they all have things in common, such as that the PLOT key produces

graphs, that the SYMB key puts you into a screen used to enter equations and

rules, and that the NUM key displays the information in tabular form.

There are ten standard aplets available via the APLET key. More can be

created by you or obtained via the Internet (see pages 212 & 200)

The Function aplet (see page 51)

Provides f(x) style graphs, calculus functions etc. It will not only

graph but find intercepts, intersections, areas and turning

points.

The Inference aplet (see page 150)

Allows the investigation of inferential statistics via hypothesis

testing and confidence intervals. This was not available on the

hp 38g, the original calculator upon which the hp 39g+ was

based.

The Parametric aplet (see page 100)

Handles x(t), y(t) style graphs. Can also be used to help with

vector motion.

The Finance aplet (see page 160)

Performs calculations involving time/value of money.

The Polar aplet (see page 106)

Handles r(θ) style graphs. Quite apart from their mathematical

use, they produce some really lovely patterns!
