Let me scroll down a little bit so I have a little bit more, a little bit more space, but make sure we see our original differential equation. Let's test whether, I'm gonna do it in a red color. Let's test whether f of x equals e to the x plus x plus one is a solution to this differential equation. Pause the video again and see if you can figure it out. All right, well, let's figure out the derivative here. f prime of x is going to be equal to, derivative of e to the x with respect to x is e to the x, which I always find amazing, and so, and then plus one, and the derivative of this with respect to x is just zero. And then let's substitute this into our original differential equation.
