Ordinary Differential Equations: Series Solutions and Applications

Many real-world physical systems are governed by complex differential equations that cannot be solved using basic calculus alone. This text-based course guides you through advanced analytical methods, focusing on power series solutions and their practical applications in science and engineering. You will develop a strong intuitive grasp of how to approach equations that resist standard integration techniques. By reading through clear explanations and working through structured mathematical proofs, you will transition from basic calculus to solving sophisticated differential equations. This course bridges the gap between theoretical mathematics and practical engineering applications. What you'll learn: - Understand the foundational terminology of higher-order ordinary differential equations. - Apply power series methods to solve differential equations near ordinary and singular points. - Solve classic mathematical models including Bessel's and Legendre's equations. - Analyze physical systems, such as oscillating circuits and mechanical waves, using series solutions. - Explore modern numerical approximation concepts that complement analytical techniques. - Practice solving complex equations through step-by-step written exercises. This course begins with essential definitions and a review of power series basics before moving into detailed, step-by-step derivations of key solving techniques. You will learn entirely through written text, detailed mathematical breakdowns, and guided practice problems. This course is designed for students, engineers, and science professionals who have completed basic calculus and want to expand their mathematical toolkit.
