Central Limits Theorem   (details) 39/40 ENG   41KB/2KB
One of the most fundamental theorems in the study of statistical inference is the Central Limits Theorem. This states basically that the means of successive random samples taken from a population will be normally distributed whatever the underlying parent distribution. This aplet illustrates this and that the standard deviations are related by ratio. Sampling can be done from different parent distributions and the resulting collection of means compared to the equivalent Normal distribution. It is fairly slow to execute because of the need for repeated sampling but would be quite useful to teachers.

This is a program, written in French but easily understandable, that allows you to automate the entry and playing of music.

The result is stored into L1 (one of the lists) and can then be played. Quite simple but easier to use than programming it yourself.

Grayscale Tunnel for the HP 39gII 1.0   (details) 39/40 ENG   2KB/9KB
Grayscale tunnel game. As of March 2013, there is no working way to transfer programs to the PC. The provided ways do not work, because the firmware used by the emulator required to transfer files isn't available anywhere for download for the calculator and both must have identical revision numbers in order to accept programs from each others. The connectivity kit provided with the calculator only lets you view/edit code. This is why the game is provided in source code form. This game will most likely only run on the HP 39gII released in 2012.

Hyper Matrix 1.0   (details) 39/40 ENG   2KB/4KB
Lets students work with matrix calculations as quickly as possible. When it starts, it displays a list of matrix calculations you can perform (add, subtract, inverse, etc.). After choosing one, the program asks you for two matrices, namely M1 and M2. Once that's done the answer is automatically displayed and stored in M1. I've even programmed it to detect when certain calculations aren't possible. While this may sound like a lengthy process, it does take place a lot faster.

Just note the decimal number next to the library in the MEMORY view and then type UNLIB(number) in the HOME view. Providing that it's not in use then it will be gone. You can't delete the UnLib library itself but since it's only 189 bytes in size that hardly matters.
