13 - Reducible Second Order ODEs - Missing X

THIS LECTURE IS OPTIONAL. YOU WILL MOST PROBABLY NOT NEED THIS FOR THE TEST, WE WILL ONLY BE DEALING WITH CONSTANT COEFFICIENT ODEs. You can skip this lecture if you feel like it.

Let's do the same substitution: Let's see where it gets us.

That's about it for differential equations!

It's time for the boss fight. Which is actually easier.
