Let's think about a definite integral of f of x dx. So it's the area under the curve f of x, but instead of it being between two different x values, say a and b, like we've seen multiple times, let's say it's between the same one. Let's say it's between c and c, or let's say c is right over here. What do you think this thing right over here is going to be equal to? What does this represent? What does this equal to? And I encourage you to pause the video and try to think about it.
