Well, we've seen already multiple times. If you wanna find the change in quantity, you can take the integral of the rate function of it. And so velocity is actually the rate of displacement is one way to think about it. So displacement over the first five seconds, we could take the integral from zero to five, zero to five, of our velocity function, of our velocity function, just like that. And we can even calculate this really fast. That would just be this area right over here, which we could just use a little bit of geometry. This is a five by five triangle.
