I tried to be fairly clear (without being pedantic) about definitions, hypotheses, conclusions, and where we use properties of limits.

Let's get back to Barrow later. If
Leibniz wrote that "it appeared to be proved but was incorrect", doesn't it show that he never actually claimed d(xy)=dxdy as true? And if the text we are quoting is a running diary where he felt free to improvise over a 10 day period, isn't it ungenerous to claim
2174:
Note that
Leibniz clearly states that he wishes to examine whether d(xy)=dxdy, or not. He proceeds to examine it, and comes to a different conclusion. This much emerges clearly from Baron's documentation. By no stretch of the imagination can this be described as an "error" on Leibniz's part. Does

Well I think apocryphal is too strong when he spent a couple of pages on the idea and only wrote the correct result 10 days later. See Church (2008) page 100 on about it. Especially the bit on page 101 where he says it appeared to be proved but was incorrect. Incidentally Child on page 102 seems to

Two proofs of the
Product Rule are provided. As far as I can see they are both rigorous and they are both nicely presented. However, the title of the second proof, `Rigorous Proof', suggests, to me at least, that the proof by factoring is not rigorous. The second proof proceeds directly from the

Well if you can phrase it better please do. However apocryphal refers to stories which didn't happen in real life. He though it might be true and later found out it wasn't. If he thought 7 times 8 might be 54 and later corrected it to 56 I know what I'd call it. Anyway we should be following the

The author of the proof was mechanically distributing the limits over sums and products. Then the limit in question simplifies in the next step. Whether to simplify it a step earlier, during the distribution step, is a matter of taste. For what it's worth, I prefer the current version, over the

The claim that "Leibniz himself made this error initially" is absurd, though it has been recycled in some publications more interested in amusing the students than historical accuracy. Leibniz specifically says that he would like to determine whether the rule d(xy)=dxdy applies, makes a few

Big-picture takeaway: I guess we can't just blithely assume that a garrulous / comprehensive article on a topic will automatically contain the most plausible / relevant search strings for it. Maybe a deliberate program of inclusion of keywords for every article needs to be undertaken.

There's plenty of other identities which can be called product rules. There must be 15 of them involving curls and divs and grads and what not. But I'm an opponent of pre-emptive disambiguation, so I say leave it unless there's a real need to move it. Certainly you can call this one

The justification is informal, because it uses infinitesimals in an informal way: it works under most reasonable assumptions, but what about unreasonable ones? To do it formally, you can either use limits formally (with Ξ΄ - Ξ΅ type stuff), or a formalised system of infinitesimals.

832:(Ο) bit. In other words, the product rule is merely the distributive law followed by the discarding of higher order terms. This also quickly explains the result for a multiple product; any product term with two or more derivatives will be higher order, thus discarded.

I read Child somewhat differently. My guess is that Barrow had it first, Leibniz discovered it independently, and Newton I don't know. You seem to know more about Barrow's geometrical lectures than I do; why don't you give it a try? I can participate if you wish.

the current articles doesn't discuss dudv and why this is not used In differentiable deterministic calculus but is required in stochastic calculus. Ito's product rule is not cited or referenced in article which is therefore missing discussion of important concepts.

This would be appreciated by everyone who works with operators (quantum mechanics), matrices, or just wants to apply the product rule to vector products (as 7yl4r found out already). In this respect, unfortunately, many of the math lines need reworking - anyone?
2577:
That step is OK, but the calculation confuses the infinitesimal dx, dy and their role in the symbolic notation for the derivative dy/dx. Dropping the mention of "st" in the last line is not correct if dy/dx is literally a ratio, since it may not even be real.

I think it is very unfortunate that associativity is assumed throughout this article without ever mentioning it, then, under
Generalisations suddenly the sequence of multiplicands is observed. IMHO the product rule should NEVER be stated
2991:
In the final line of the proof it seems to me that the limit applied to f(x) shouldn't be there. After all, f(x)=f(x) by definition. This is a minor thing but if it's superfluous it makes the proof more complicated than it needs to be.
