In this video, I introduce the Frobenius Method to solving ODEs and do a short example.

Questions? Ask them below!

Prerequisites: Regular series solutions of ODEs (basically those two series videos I made).

Also, one of the comments pointed out that I made a mistake at 8:45: when you plug r1=1 into the coefficient of the a1 term, you get 3! For r2=0.5 you get 1. Still, that doesn't change the fact that plugging these values of r into the other terms will give us non-zero coefficients for the a1, a2, a3, etc.
