Foundations of Differential Equations for Science and Engineering

Differential equations are the mathematical backbone of physics, engineering, and chemistry, yet they often seem intimidating to students. This text-based course breaks down complex calculus concepts into clear, manageable steps, starting with the absolute basics. You will transition from simply memorizing integration rules to deeply understanding how to model real-world change. By studying the core mechanics of differential equations, you will build the analytical skills necessary for advanced academic exams, engineering prep, and practical scientific applications. What you will learn: - Understand foundational definitions, order, degree, and the classification of differential equations. - Solve first-order differential equations using separation of variables, homogeneous equations, and integrating factors. - Apply second-order linear differential equations with constant coefficients to model physical systems. - Explore modern numerical approximation techniques including Euler's method for equations without analytical solutions. - Practice step-by-step mathematical derivations through detailed written examples and guided exercises. The course begins with essential terminology and basic calculus prerequisites before guiding you through progressively challenging solution techniques and modeling scenarios. This course is designed for students, aspiring engineers, and science enthusiasts with a basic background in single-variable calculus; no prior differential equations experience is required.
