Solving Second-Order Linear ODEs

This animation walks through solving a linear second-order differential equation with constant coefficients by forming the characteristic equation and finding its roots. It shows how real distinct roots, repeated roots, and complex conjugate roots each lead to a different form of the general solution, connecting the algebra of quadratic roots to exponential, polynomial, and oscillating solution curves. Useful for students in a first differential equations or engineering math course.
