Systems of Differential Equations for Practical Applications

Many real-world systems, from predator-prey dynamics to coupled electrical circuits, cannot be described by a single differential equation. Understanding how multiple variables interact simultaneously is essential for accurate modeling in science, engineering, and finance. This text-only course guides you from the fundamental definitions of systems of ordinary differential equations to solving them with confidence. You will learn to analyze complex behaviors, apply linear algebra concepts to differential systems, and understand the foundational theory behind multi-variable dynamic processes. What you'll learn: - Understand the fundamental terminology of systems of differential equations and state-space representations. - Solve linear systems of differential equations using eigenvalues and eigenvectors. - Analyze phase portraits and determine the stability of critical points in dynamic systems. - Apply matrix methods and decoupling techniques to simplify complex multi-variable equations. - Explore modern computational modeling concepts and basic numerical approximation methods. - Practice modeling real-world scenarios in engineering and biology using coupled equations. The course begins with core definitions and the transition from single equations to systems, ensuring you build a strong conceptual foundation. You will then progress through linear algebra applications, analytical solution methods, and modern simulation frameworks. This course is designed for beginners with a basic background in calculus who want to expand their mathematical toolkit for practical applications.
