Differential Equations: Lecture 4.4 Method of Undetermined Coefficients - Superposition Approach

This is a classroom lecture on differential equations. I covered section 4.4 which is on the method of undetermined coefficients. I hope this is helpful. These lectures follow the book A First Course in Differential Equations by Dennis Zill. This is a great book for learning differential equations. Here is the book https://amzn.to/4ajOMyW (affiliate link).
