So the second derivative is going to be e to the x, e to the x plus two times e to the x, plus two times e to the x, is indeed going to be equal to three times e to the x, three times e to the x. This is absolutely going to be true. E to the x plus two to the x is three e to the x. So y two is also a solution to this differential equation. So that's a start. In the next few videos, we'll explore this more. We'll start to see what the solutions look like, what classes of solutions are, techniques for solving them, visualizing solutions to differential equations, and a whole toolkit for kind of digging in deeper.
