*1. Introduction: The Importance of Error Analysis*

Numerical simulations are essential tools in many fields, from engineering and physics to finance and biology. They allow us to approximate solutions to complex problems that are often intractable analytically. However, numerical solutions are rarely exact. Errors are introduced at various stages of the simulation process. Ignoring or neglecting these errors can lead to misleading or even incorrect results, potentially with significant consequences. Therefore, understanding and controlling errors is paramount for reliable simulati ...
