A Calculus Collection - Leibniz


Selections from the 1684 volume of "Acta Eruditorum."

Leibniz's paper comprises pp.
467-473 and Plate 12.  This was the first publication of the rules for finding a derivative.

The symbol for equality
(=) was not in common usage at that time.  In the following rules Leibniz used the Latin abbreviation
"œqu"  for "aequales" meaning the modern (=) symbol and (--) for subtraction.  Look for . . .
Aequales

L'Hospital on Leibniz
  Button L'Hospital on Leibniz:

"I must here in justice own, (as Mr. Leibnitz (sic) himself has done in Journal des Scavans for August, 1694) that the learned Sir Isaac Newton likewise discovered something like the Calculus Differentialis,
as appears by his excellent Principia, published first in the year 1687 which almost wholly depends upon the use of the said Calculus.

But the method of Mr. Leibnitz's is much more easy and expeditious, on account of the notation he uses, not to mention the wonderful assistance it affords on many occasions."
