# Top 15 dating methods

Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology.

I've got the function y is equal to x minus 3 squared times x minus 1.

And what I want to do is think about rotating the part of this function that sits right over here between x is equal to 1 and x equals 3.

It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.

Thus, from the oldest to the youngest, all archaeological sites are likely to be dated by an appropriate method.

And x equals 3 and x equals 1 are clearly the zeroes of this function right over here.

And I want to take this region and rotate it around the y-axis. And the height right over here is going to be the value of my function. In this case, f of x is x minus 3 squared times x minus 1. Well, the radius right over here is just the horizontal distance between the y-axis and that x. So the circumference, in this case, is just going to be 2 pi times x. And so what is going to be the surface area of the outside?

In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.

But this method is also useful in many other disciplines.

It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others.

Nevertheless, the range of time within archaeological dating can be enormous compared to the average lifespan of a singular human being.

And what happens if we were to rotate this rectangle? What happens if we rotate this rectangle around the y-axis along with everything else? So it's going to look something not too dissimilar to that right over there. And then if we multiply the area of the outside surface of our cylinder by that infinitesimally small depth, then that'll give us the volume-- I shouldn't say cylinder-- of our shell. Well, it's going to be 2 pi times the radius of that shell. I'm not worried about this top part and the bottom part.
