Key Skills: Difference and Differential Equations

☕️ Buy Me A Coffee: https://buymeacoffee.com/kosaksi_pasa In this video we walk through the key ideas behind difference and differential equations and how they are used to model dynamic systems over time. We cover the structure of first-order equations, methods for solving them, and how discrete-time and continuous-time models compare. You’ll see how these concepts connect: how difference equations describe changes across discrete time periods while differential equations model continuous rates of change. We also explore why these tools are fundamental for analysing growth, stability, equilibrium, and dynamic behaviour in economics, physics, biology, and applied mathematics. A quick, clear walkthrough of the core techniques behind difference and differential equations used throughout dynamic modelling and applied mathematics.
