![]() And so, notice, from our first intuitive sense, I can definitely draw this function as we go through x equals c And, we care about theīehavior right over here when x is equal to c. So let's say this right over here is y is equal to f of x. We're continuous at a point, and see how this more And then let's thinkĪbout a couple of examples where it doesn't seem like By our picking-up-the-pencil idea, it feels like we areĬontinuous at a point. Value of our function there, then we are continuous at that point. It's saying look, if the limit as we approach c from the left and the right of f of x, if that's actually the ![]() ![]() But let's just thinkĪbout what it's saying. To show if, and only if, the two-sided limit of f of x, as x approaches c, is equal to f of c. So we could say theįunction f is continuous. ![]() So the formal definition ofĬontinuity, let's start here, we'll start with continuity at a point. Well let's actually come up with a formal definition for continuity, and then see if it feels intuitive for us. And so that is an intuitive sense that we are not continuous How do I keep drawing this function without picking up my pen? I would have to pick it up, and then move back down here. Let's see, my pen is touching the screen, touching the screen, touching the screen. This function would be very hard to draw going through x equals c But if I had a function that looked somewhat different that that, if I had a function that looked like this, let's say that it isĭefined up until then, and then there's a bit of a jump, and then it goes like this, well this would be very hard to draw at. I can go through that point, so we could say that ourįunction is continuous there. So I could just start here, and I don't have to pick up my pencil, and there you go. If I can draw the graph at that point, the value of the function at that point without picking up my pencil, or my pen, then it's continuous there. What I just said is not that rigorous, or not rigorous at all, is that well, let's think about Graph of that function at that point without And the general idea of continuity, we've got an intuitive idea of the past, is that a function isĬontinuous at a point, is if you can draw the No mistaking that it’s from a new record.Going to do in this video is come up with a more rigorousĭefinition for continuity. Known as one of country’s more rock-oriented artists, Aldean says he decided to “shake it up” with “Burnin’ It Down.” “Let’s put out something that when people hear it, there’s no mistaking what song it is, and who sings it. “We could have come out with one of the rock-oriented things we’ve always done: ‘Hicktown,’ ‘Johnny Cash,’ ‘She’s Country,’ ‘My Kinda Party,’ ‘Take a Little Ride.’ Those were the five singles that we’ve come out with It’s a big tempo thing.” “I think a lot of people were surprised and that was sort of the idea,” Aldean tells Rolling Stone Country of the track, which is currently Number One on Billboard‘s Hot Country Songs Chart. The stoic singer found it with the sultry jam “Burnin’ It Down,” which he performed last night on Jimmy Kimmel Live. When Jason Aldean was selecting the first single for his upcoming album, Old Boots, New Dirt, out October 7th, he wanted something that stood apart from the singles that launched his past albums.
