Triangle program that uses 3 connected values to solve for all sides and angles, supporting Side Angle Side, Angle Side Angle, or Side Side Side, and then draws a scaled triangle on the display with values.
Finds the three sides and angles of a triangle.
This library contain 12 additional trigonometric functions, COT, SEC, CSC, ACOT, ASEC, ACSC, COTH, SECH, CSCH, ACOTH, ASECH and ACSCH. Documentation in HTML & Word 2000 formats.
A trig library which will solve for any valid triangle. It uses a modified version of INPUTLINE to maintain the screen. Inputs and outputs can be in either Deg.Dec or HMS, with options for echoing to and from the stack. Supports normal display options fraction mark, and std/eng/sci, etc. Written in System RPL and compatible with ROM 2.0 and up.
This program calculates the unknown sides and angles of a given triangle once a sufficient amount of information has been entered. In addition, the area of the triangle is calculated and a scaled diagram is displayed. For the 50g. 
Turing machines are extremely basic symbol-manipulating devices which, despite their simplicity, can be adapted to simulate the logic of any computer that could possibly be constructed. This program can simulate steps processing a basic Turing Machine script, showing the tape after each step.
Allows a complete customization of the UNITS system. One may add user-defined units to the unit categories. User units are treated like built-ins, i.e., the famous 3-fold functionality of a unit key applies to an integrated user-units as well. In addition, one may reorganize a units menu, i.e., reorder it or purge not needed units. The same can be done with the whole bundle of unit directories to which new ones may be added ad libitum. Now contains HTML documentation.
A complete set of unit utilities (utools). Includes a full-screen menu for fast access to 54 (49g+/50g) or 42 (HP 49G/48gII) user-selected units, a configurable inverse UBASE command, handling of general non-SI base units (cgs, English, Planck etc), re-implementations of MUC and other HP 48 unit utilities. Requires ROM 2.00 on the 49g+/48gII/50g.
Performs material resistance calculations by taking a square matrix and calculating its eigenvectors and eigenvalues, just like EGV, but it changes the vectors for the unitary ones (with the same direction) and, if three-dimensional, checks if they form a direct reference system..
Given random variables, calculates the expected value (a type of average) and variance (a measure of the "spread", or extent to which the values are dispersed).
Works with vectors.
This a library that contains four numeric methods. These methods are useful for finding roots of any expression. The methods are: bisection, Regula Falsi, fixed point and Newton-Raphson. The result is given in the stack, and every step that the method did to find the root is presented in a matrix. This matrix is stored in the current directory with the name: "Tabla". Messes with your calculator's settings.
Takes out the Wronskian from any number of functions that are put in.
