3D Parametric Function Plotting 1.0   (details) Prime ENG   173KB/7KB
ScreenshotPlots a colored 3-dimensional parametric equation on an HP Prime of the form z=(t,u) where t and u are angular parameters in degrees, generally varying from zero to 360 degrees. Your Prime must be set to Degrees mode in both CAS and Home. The program will also ask for the number of slices in t and u, I generally use 40 for both. The viewing angle for the sample plot is 5 degrees for the x-axis and 25 degrees for the z-axis. There are sample functions for a toroid (doughnut), sphere, orbital (modulated sphere) and spirals. The program is based on an old Byte magazine article discussing the mathematical principles behind 3D plotting.

A Fluorescent Light Experiement   (details) Prime ENG   303KB
Experiment showing how the Prime can be used with the HP StreamSmart 410 and a light sensor to measure the frequency of a fluorescent light.

Also has useful information on how to export data from Excel to the Prime.

Card Sharks Odds   (details) Prime ENG   3KB/2KB
The game show Card Sharks may have long been off-air except for reruns on GSN or BUZZR (or even finding videos on YouTube), the game show is still popular. It is a simple game involving a standard deck of 52 cards. The object is to predict whether the next card is higher in rank or lower in rank than the preceding card. In Card Sharks, aces always count as high. Along with aces, twos are very desirable, while eights are the worst cards in the deck. The program CSODDS tracks the odds of whether the next card is higher or lower. CSODDS assumes a 52 card deck (no jokers).

Mandelbrot   (details) Prime ENG   47KB/5KB
ScreenshotThis is a very basic and straight forward approach to programming the Mandelbrot set on the Prime. It just shows how programming and using complex numbers/variables in a program work on the Prime. It is in no way optimized for speed, neither mathematically nor in terms of implementation. Also, it's not a Prime App (thus not using the Symb/Plot/Num and their Setup keys) and has no interactivity (like zooming) at all. The area of the Mandelbrot set is defined by setting the corresponding variables in the source code. Take it as a starting point for your further explorations, be it in Prime programming or in math. And feel free to expand it and maybe make an App out of it with interactivity.

RTable 1.0   (details) Prime ENG   153KB/86KB
The functions contained in this program use the Spreadsheet application to provide an analog of the Data Frame object in the R language and environment for statistical computing and graphics. In particular, the functions provide a means of loading a spreadsheet from a CSV file and saving spreadsheet content to a CSV file. Additional table management functions are provided, for example to add or remove rows or columns. RTable uses the RFC standard for CSV files, but you can specify changes such as a different field delimiter character (e.g. tab) or fixed-column fields. You can choose which attribute of a cell to load or save, such as name or formula, but only values are loaded correctly in this release. A small number of frame related functions are provided, like names and ncol. Comprehensive PDF documentation included.
