Review of lesson 5.4 for MA 262 (Linear Algebra & Differential Equations) at Purdue University. Content based on class textbook Differential Equations & Linear Algebra by C. Henry Edwards and David E. Penney (ISBN: 9780536264923). 5.4 covers the application of differential equations (DEs) to describe mechanical vibrations, including mass-spring-dashpot systems, masses on springs, simple pendulums, free damped motion, free undamped motion, and overdamped and underdamped cases. Derivation of ap...
