Numerical Analysis

Feras Awad, Feb 24, 2026

This collection of GeoGebra applets is designed to bridge the gap between theoretical numerical methods and practical computational visualization. By transforming static algorithms into interactive simulations, this book provides a dynamic environment to explore error analysis, root-finding iterations, polynomial interpolation, and the precision of numerical integration.
