These are some fun projects showcasing some fun experiments I've done in my free time to understand and play with the math I've learned in High School.
This is a fun small program that can run Euclid's algorithm, which finds the largest common denominator of a set of numbers (by subtracting the largest one with the smallest one over and over). In school, the algorithm was taught with only two numbers and by hand. Using computer automation, it proves very simple and rudimentary to implement, while also working for infinitely large sets of integers.
This program was originally written to automate a tedious assignment of euler's step method, which uses small steps (ideally approaching zero) multiplied by the derivative in each node to approximate the course of a function, while not knowing the function itself and only the relation of the derivative y' to the function y in terms of x and y. It proved very interesting. Aprroximation of euler's number e is, of course, possible with this program, which is pretty cool.
