And so that would be the, roughly, that would be the area under the curve over that very, very small change in time. So what we really wanna do is find the area under this curve from t equals two to t equals five. And we have seen multiple times in calculus how to express that. So the definite integral from t is equal to two to t is equal to five of this expression of e to the 1.2t minus two t dt, dt. So if we just evaluate that, that will be the answer to this first question. So what is this going to be? Well, let's actually work it out.
