They are: Versine (VERS(X); 1 – cos x), Coversine (COVERS(X); 1 – sin x), Haversine (HAV(X); sin(x/2)^2), Normalized Sampling (NSINC(X); sin(π * x)/(π * x)), Exsecant (EXSEC(X); sec x - 1), Gundermannian (GD(X); atan(sinh x)), Inverse Gundermannian (INVGD(X); asinh(tan x)), Dilogarithm (DILN(X); ∫ (ln t / (t – 1) dt, 1, x)), Exponential Polynomial (EPOLY(N, X); Σ(x^j / j!, j, 0, n)), Hypotenuse of a Right Triangle (HYPER(A,B); √(a^2 + b^2)), Langevin Function (LANGEVIN(X); 1/tanh x – 1/x), General Mean Function (GENMEAN(N,A,B), N = 1, arithmetic mean, N = 2, root mean square, N = -1, harmonic mean, (a^n + b^n) / 2)^(1/n)), and Logarithmic Integral (Li(X); Ei(LN(x))). |
Transforms the current time into RGB form and displays the color as the background. You can treat it like a screensaver. Inspired by the ColourClock by Jack Hughes. The original design belongs to lookatjack.com.
A compact and elegant program that allows the customization of the soft keys in a consistent manner, whether for the global environment or for each Prime app. Now it is possible to have at any entry window your preferred characters or commands, e.g., Greek characters for scientific writing, preferred units for fast unit conversion or fast access commands with customized entry. Menus are swiftly managed with the four ways of the directional pad (left/right/up/down).
Adds key assignment to EEX to allow sto with 2 clicks. In other words, press EEX+EEX for EEX. Press Shift+EEX+EEX for ▶. Press EEX+a..z for ▶a..z (no ALPHA on needed). It also detects if a char exist before the expression/number to be wanted to store and uses Ans▶ or ▶ according to situation. When sto mode is on, ▶a..z symbol is displayed in the status bar. Additionally it works with uppercase in non-CAS mode.

Generates random colors or defined or randomly defined tone of colors by sections defined by users. You can divide the screen into something as 36*24, 4*4...with a maximum of 320*240. Please wait for updates that will allow you to touch the screen and return the displayed colors in RGB or HEX form.
Program to search inside current program text, all programs, current note text, and all notes. May have issues on the G2.
RPN Calculator app designed for typical math operations and optimized for survey calculations with angle, distance, area and volume unit support. Converting between units is simple, and results can be stored in variables for later use. Now supports 2D/3D vectors and has an improved workflow for storing and purging variables.
A Screen Capture utility that saves your calculator screen as a PNG file to the app's Files folder. Uses a user key definition to accomplish the task from most calculator screens. Includes a File Manager to delete and view existing screen captures.
