EULER, LEONHARD.

Exposition de quelques paradoxes dans le calcul integral.

(Berlin, Haude et Spener, 1758). 4to. No wrappers as issued in "Memoires de l'Academie Royale des Sciences et Belles Lettres". tome XI, 1756 pp. 300-321 and 1 folded engraved plate.

First appearance of this paper in which Euler examines some peculiar differential equations that can be solved through the rather paradoxical method of integration by differentiation. He presents four such problems, which were found to all be members of the same family of differential equations, thus this presentation will focus on reworking several of these problems to make use of this generalization.

Together with a paper by Eulers son (Euler le Fils - Johann Albrecht): Des Cerfs - Volans. Traduit du Latin. Pp. 322-364 and 3 folded engraved plates. - Johann here exposes his electrical theory in relation to kites, and indicates that kites were not only children's toys but had been used by the celebrated Romas in his electrical experiments.
