Let me make it clear, we've got parentheses there, and then we have our dx. So once again, even over this interval, when f of x was above the x-axis and g of x was below the x-axis, it still boiled down to the same thing. Well, let's take another scenario. Let's take the scenario when they are both below the x-axis. Let's say that we wanted to go from x equals, well, I won't use e since that is a loaded letter in mathematics, and so is f and g. Well, let's just say, well, I'm kind of running out of letters now. Let's say that I am gonna go from, I don't know, let's just call this m, and let's call this n right over here. Well, n is getting, let's put n right over here.
