Overview

This repository contains several Python scripts and Jupyter notebooks for numerical analysis and solving differential equations. The tools included are focused on Fourier series, solving second-order ordinary differential equations (ODEs), and using the Euler method for ODEs. Additionally, there is a script for modeling uranium decay.
