And we know how to think about displacement. Velocity is your rate of change of displacement. And so if you wanna figure out your displacement, you're between two times, you would integrate the velocity function, so this is going to be the integral from t equals two to t equals seven of our velocity function, v of t dt. This would be our displacement from time two to time seven. So if they said what is our change in position from time two to time seven, it would be just this expression. But they want us to figure out, or they want Divya to figure out, what is the particle's position at t equals seven seconds? So what you'd wanna do is your position at t equals two, and we know what our position at t equals two is.
