@geeteh49522 жыл бұрын
this may be a stupid question but how does the chain rule give you (dx/dt)(da/dx) from da/dt
@turksvids2 жыл бұрын
You're probably more familiar with thinking of it as d/dx(f(g(x))) = f'(g(x) * g'(x), but what about d/dx (f(u)) = f'(u)*u'? In that notation we know that f is a function of u, so we can find df/du and we know that u is a function of x, so du/dx makes sense. So we can rewrite d/dx (f(u)) as df/du * du/dx. So if A is a function of x and x is a function of t, we'd have dA/dt = dA/dx * dx/dt. Hope this helps!

A is the rate, is the rate increasing? It’s like being given f and asked if f is increasing. Gotta look at he the sign of the derivative. They kind of love these types in recent years so definitely read carefully! Hope this helps!
@usdescartes2 жыл бұрын
Question regarding 3c: why not include both endpoints, making it [0,5]? Even without digging too far into the definition of decreasing on an interval, if NOTHING else, isn't g'(0) = -1 < 0? I don't THINK the AP scoring rubrics typically care about distinctions like "strictly decreasing," so I would think that at the very least, the correct interval on which g(x) is decreasing is [0,5). (Then, taking it a step further to what I believe is the currently accepted view by the AP Curriculum folks, is that, for instance, Cos(x) is decreasing on [0,π] and is increasing on [π,2π] because for every point in [0,π], we know a > b implies Cos(a) < Cos(b). And [π,2π], we know a > b implies Cos(a) > Cos(b).) Or is it that at the AP Reading, the rubric will allow for combination of endpoint inclusion, exactly because it doesn't matter huge amounts, teachers and books might say different things, etc.? Thanks!
@turksvids2 жыл бұрын
Yeah, as I mentioned in some other comment (but maybe on a different video?), if I could do it again I'd include 0 for sure. On the other issue, I'm just going to wait for their scoring guidelines on this one and do whatever they do here in the future. I do not typically include end points because of the justification that I almost always use, which is to say that a function is increasing if f' > 0. So reading it the way I write it, if I say a function is increasing on [0,5] because f' > 0 there, then I'm wrong if f'(0) or f'(5) = 0. I've already started switching it up, though, for myself. I think in the future I will write something like, Since f'(x) > 0 on (0,5) (in my made up example, f'(0) = f'(5) = 0), therefore f(x) is increasing on [0,5]. I have no idea what happens at AP Readings, but I'll be interested to see what they come up with specifically at x =5 for this problem.

@turksvids2 жыл бұрын
Although the values of r and h that are given at the specific time have the relationship that r = 2h, there's nothing in the problem that suggests that's always the case, so we shouldn't assume it. If you don't make the assumption and take the value of r'(3) from the table of values, you'll get the solution I did. Hope the exam went well for you!
