Description

This file contains 13 programs for the CASIO fx CG50: AFRAC, a program that uses continued fraction, and can give you a good approximation, as well as the exact value for denominators well above a million. APRIME: A prime finder which divides out all even numbers as well as numbers divisible with three, from number five. CFRAC, a simple and fast routine for fractions. DIVISOR: Gives the divisors of an integer, using the Augment(-utility. It also shows you the sum of all the divors, except the biggest one. LCM: The algorithm that Euclid found. Also shows the GCD. PERIOD: Shows you the period of a fraction. POLYDIV: A simple and concise program for dividing polynomials. POLYMULT: As simple as possible a program for multiplying polynomials. PRIME1: An elementary prime factor program. Shows the result as a list. PRIME2: A prime factor finder that uses a list of numbers, a piece of Erathosthenes sieve, to divide out the primes. Very fast. PRIMES and PRIMES1, are two programs that gives you the prime numbers in an interval of your choice. SOLVERY: This is the main attraction in the collection. A polynomial solver that can find factors like 5x^6-3, and of course factors all the way down to 2x-1. It can also find second degree factors like: 2x^2-8x-7, 1x^2+8x-1. You input coefficients of the equations left part as a list. The right part has to be null. The result is also showed as lists. Remember that it is the size of the list that determines the degree: 5X^6 - 3, comes out as {5 0 0 0 0 0 -3}. UPDATE: The program has got a proper routine for deciding the divisors of the first degree coefficients in the second degree factors. But I can not say it speeded up the program. At least it finds all the second degree factors now. {72,189,-104,-198,165,-34} takes around 5 minutes and 20 seconds, to solve to: {24,23,-17} and {3,5,-7,2}. Which the older versions did not manage.
