In this video we use mathematics to model war. We will see a system of differential equations that leads to something called Lanchester Square Model and helps explain the phenomenon of Lanchester Square Collapse, where wo armies that were originally relatively comparable end up having one side collapsing. We use a differential equations technique called eliminating t to derive hyperbolic solutions. This model is contrasted in Lanchester's Linear Model.

The paper using Lanchester Square Model to analyze the battle of gettysburg by Armstrong and Sodergren is here: https://onlinelibrary.wiley.com/doi/f.... I also used the mobile game 2D Battle Simulator for animations.
