In this lesson, we delve into the theory of general second-order linear homogeneous ODEs, covering superposition, uniqueness, and Wronskians. The focus of the lecture is on the linearity of the equation and finding independent solutions, which are necessary to determine a linear combination of the solutions that satisfies all initial conditions. The superposition principle is introduced, which states that any linear combination of solutions to a linear homogeneous ODE is also a solution. The lecture concludes by addressing the initial value problem and how this family of solutions can be used to satisfy any initial condition.
