| Some basic number theory algorithms, allowing you to find the sum, difference and product (mod n), represent integers as the sum of two squares or as the sum of a square plus a multiple of another square, find the gcd, directly or step by step, of two numbers, determine if two numbers are relatively prime, use Euler Phi function to determine the number of relatively prime numbers there are to an integer, find multiplicative inverses (mod p), solve linear equation (mod n), solve a system of equations with multiple moduli and remainders (Chinese Remainder Theorem), use the Fast Powering algorithm f exponentiation (mod n), find primitive roots (mod p), find quadratic residues of an integer, determine if an integer has a square root (mod p), if so, find the square root (mod p), use the Jacobi Symbol, apply the Gauss Criterion, solve any quadratic equation (mod p), find idempotents of Z/nZ, find invariants of indempotents in Z/nZ, use the Solovay-Strassen, the Miller-Rabin test or the "wheel" for testing primality, factor an integer into product of primes, find the next prime starting at any integer, find the next prime with remainder r, modulo n. The HP 49 version has additional programs added to generate Pythagorean triangles, generate the Egyptian fraction decomposition of any fraction, and find the smallest solution to the Pell equation x*x - N*y*y=1, for fixed N>1. |

CAD geometry and 3D design program.
This program gives the formats for integrals and derivatives for calculus.
A very simple program. It improves multiplications and divisions, showing them exactly as we make it in paper.
Program to power a matrix by any value. Written in User RPL.

Program to solve e^Matrix using the Numeric Method of McLaurin's Series. Written in User RPL.
A right triangle solver. Given any two sides, can return the pitch and the other side. Given the pitch and one side can return the other two. Works in decimal feet. Pitch expressed in inches rise per one foot of travel. Numbers entered in Feet.In16 mode. Handy display program shows lengths in Feet'-In f/16" in the status line. (see screenshot).
Allows one to store mathematical formulas so that they are well organized. Includes source code.
Analytic geometry program.
All the material of algebra, physics, chemistry, and calculus corresponding to the first year of civil engineering at the University of Concepcion, Chile.
This program calculates interpolated values from a sheet, to find the intermediate value.
Linear interpolation library.
