Differential Equations in Science and Engineering

Differential equations are the mathematical language used to describe how the physical world changes, from fluid dynamics to electrical circuits. Understanding how to solve and analyze these equations is essential for any aspiring scientist or engineer. This text-based course guides you from foundational mathematical concepts to solving real-world differential equations. You will develop a strong intuitive understanding of rates of change, learn classical analytical methods, and gain an introduction to modern numerical techniques used in engineering today. What you'll learn: • Understand the core terminology, classification, and physical meaning of differential equations. • Solve first-order and second-order ordinary differential equations using analytical methods. • Apply differential equations to model real-world systems in physics, chemistry, and biology. • Explore modern numerical approximation methods and conceptual computational workflows. • Practice your skills through guided written exercises, step-by-step derivations, and self-assessment challenges. The course begins with essential terminology and foundational definitions before guiding you through analytical solving techniques, practical modeling scenarios, and modern numerical approaches. You will learn entirely through clear written explanations, structured mathematical proofs, and comprehensive practice problems. This course is designed for beginners, students, and self-learners in science, technology, engineering, and mathematics (STEM) fields who have a basic background in basic calculus.
