In previous videos, we have talked about how Christianity evolved and developed under the Roman Empire. In particular, we saw that as we entered into the 4th Century, Christianity continued to be persecuted, in particular by the emperor Diocesan, who had …

We’re told a quadratic function f has a vertex at (-4, 7) and passes through the point (-2, -5). Write an equation for f in vertex form. So pause this video and try to work that out before we do that together. All right, so first let’s think about the ge…

In 1819, American author Washington Irving published a short story about a man named Rip Van Winkle. In the story, Rip lived in a sleepy village in the Catskill Mountains of New York, where he spent his days hanging around the local tavern, the King Georg…

So let’s use integer chips again to start exploring a little bit more when we deal with negative numbers. So let’s say we wanted to compute what negative one minus 7 is. See if you can pause this video and figure that out using integer chips. Well, let’s…

Let’s say we have the function f of x, which is equal to cosine of x to the third power. We could also write it like this: cosine of x to the third power. We are interested in figuring out what f prime of x is going to be equal to. So, we want to figure o…

Today, we’re going to be talking about the reaction quotient Q. In this video, I’m going to go over how you calculate Q and how you use it. We’re going to start with an example reaction between sulfur dioxide (SO2) gas, which will react with oxygen gas. …
