174050926Petropoli St. Petersburg Typis Academiae 1740. 4to. No wrappers. In: "Classes Prima continens Mathematica. Commentarii Academiae Scientiarum Imperialis Petropolitanae" Tomus VII ad Annum 1735 &. Euler's papers: pp. 135-149 150-161 174-183 a. 184-200 and 2 engraved plates. Clean and fine. <br/><br/><em>First printing of 4 importent early papers by Euler. Enestroem: E42 E43 E44 a. E45.E42: This is Euler's second paper on the "Brachistochrone problem".E43. Here Euler introduces THE EULER CONSTANT. "The Euler-Mascheroni constant also called Euler's constant is a mathematical constant recurring in analysis and number theory usually denoted by the lowercase Greek letter gamma."E44: "This is an extensive paper that develops a method for finding a family of curves arising from the constant of integration of dz = Pdx which is treated as the second variable; the rudiments of partial differentiation are presented and there is an extensive survey of homogeneous functions centred around what is now know as Euler's Theorem for such functions. The origins of this paper would seem to be Proposition 15 of Vol. 2 of the Mechanica relating to families of tautochronous curves where an integration relying on Euler's Theorem is required." Ian Bruce.E45: Here Euler introduces the FUNCTION NOTATION fx. "This is an equally extensive paper that continues the development of methods for finding a family of curves arising from the constant of integration of dz = Pdx which is treated as the second variable. A method is developed for finding the modular equation for the first order equation that is extended to cover a number of cases; this in turn is extended to second and higher orders. The method involves finding suitable functions to integrate starting from a part of the modular equation that is integrable so that the whole equation is of this form. This paper is noteworthy in addition as it seems to be the first in which the function notation albeit in a slightly different form from the modern meaning is introduce. I have not been able to check all the equations at this stage."Ian Bruce.This section also contains DANIEL BERNOULLI: Demonstrationes theorematum svorum de oscillationibus corporum filo flexili connexorum et catenae verticaliter suspensae.
