[00:00:00]Here is x² + z² = 1, and then it gets cut by the plane. The equation of the plane was x + y = 2. So, that plane comes in and cuts the cylinder, and then when you're figuring out your surface integral, there's a total of how many surfaces? One, two, very good, three, right? Okay, so let's visualize it. Here's the plane, x + y = 2.

[00:00:26]Wow, can you see three surface integrals that we have to compute? The back, the actual cylinder, and then the surface that's cut by the plane, okay? This is how they learn calculus right here.
