Understanding Second Order Linear Homogeneous Differential Equations

The video tutorial explains how to solve a second order linear homogeneous differential equation using the method of reduction of order. It begins with an introduction to the equation and the method, followed by a detailed step-by-step process to find the second solution. The tutorial covers the application of the product rule, substitution, and simplification of the differential equation. It then demonstrates solving the resulting first order equation using separation of variables and concludes with determining the general solution using linearly independent solutions.
