In this video, I discuss perturbation methods in ODEs (ordinary differential equations). Perturbation methods become necessary in differential equations which are otherwise linear, but are 'perturbed' by a small complicated (usually nonlinear) term. I discuss the steps behind performing perturbation methods, and finish the video with an example problem of using perturbation methods to solve a second-order ODE.
Questions/requests? Let me know in the comments!
Prereqs: my playlist on topics in differential equations ( • Topics in Ordinary Differential Equations ) is helpful, but ultimately, knowing how to solve linear ODEs with constant coefficients is enough.
