So, we would have one over w minus 300, dw dt, the derivative of w with respect to t, is equal to, well, I divided this side by w minus 300, so it's equal to one over 25. Now, I wanna get the dt's on this side, so let's multiply both sides by dt. View the differential as just a very, very small change in t. And so, we get, and I'm a little bit imprecise with my notation here, but this is one way that you can think about it when you are dealing with differential equations like this, separable differential equations. You have one over w minus 300, dw, let me make sure that the dw doesn't look like it's in the denominator, dw, is equal to one over 25 dt. And now, we can integrate both sides, which is essentially just saying that we're taking, since this is equal to this, that each little increment of w times this is equal to each little increment of dt times one over 25. We can then say, well, if we sum up all of the increments of w times this quantity, if we sum up the infinite number of infinitesimally small increments, that would be the same thing as summing up all of these characters, because each of these characters is really the same as each of these characters. So, let's do that sum.
