Leibniz did use this notation for instance in his paper Supplementum geometriae practicae, Acta Eruditorum, April 1693, p. 179 (Google Books link):

I just wrote a paper going through the case against the geometrical algebra and arguing that the modern consensus against it is ill-founded and an associated blog post. But my opinion is a minority ...

The differential calculus for rational functions can be reduced to finding roots of polynomials. Such methods were used by Fermat and Descartes. See problems 12.3-12.5 of my history of mathematics ...

According to the Mathematics Genealogy Project (https://genealogy.math.ndsu.nodak.edu/search.php) database, the following universities have awarded three or more mathematics PhDs for dissertations ...

The reference is probably to a treatise sent to Huygens on 5 October 1691, where Leibniz says (and illustrates with several examples) that "Whenever the subtangent [$=y/y'$, but it would also work for ...

Leibniz states the product rule in his first paper on the calculus (1684). It's in the middle of the fist page (page 467) as can be seen here: https://www.maa.org/press/periodicals/convergence/...

Yes. The menstrual cycle is surely one of the "some of our functions" that Darwin speaks of in this passage from Chapter VI of The Descent of Man, and Selection in Relation to Sex: The ...

Insofar as Barrow realised the first theorem, he also realised the second. Barrow's theorem X.11 can be interpreted as FTC1 $$\frac{d}{dt}\int_{a}^t y(x)dx = y(t)$$ while his theorem XI.19 can be ...

The assumption that people believed Aristotle’s law for so long is highly questionable. Aristotle’s law occurs in a philosophical context. He introduces it in order to argue that there can be no such ...

One argument is that terrestrial objects are made up of the four elements earth, water, air, fire, and out of these the first two are "heavy" elements whose natural motion is rectilinear motion toward ...

Hooke did propose the inverse square law to Newton, and even the program of ”compounding the celestiall motions of the planetts of a direct motion by the tangent & an attractive motion towards the ...

Johann Bernoulli explains the idea of a direction field quite explicitly (Modus generalis construendi omnes aequationes differentiales primi gradus, Acta Eruditorum, November 1694). He focusses on ...

One popular type of salon amusement was spectacular scientific experiments such as sending electric shocks through a line of people holding hands, tricking spiders into eating anything, making ...

“Geometry … teaches us the use of the rule and compasses.” Vitruvius, De architectura I.1.4. “I describe a circle with the compass. … With the straight ruler I set to work to inscribe a square within ...

Leibniz did indeed describe a mechanism for tracing the solution to any differential equation of the form dy/dx=f(x) using tractional motion. For a detailed explanation, see Viktor Blåsjö, The myth of ...
