The invention of the calculus and its early exploitation was certainly due to Newton and Leibniz, but the invention of classical analysis was very largely due to Leonhard Euler, of Basel, who worked mainly in St. Petersburg. He was the student of Johann or Jean Bernoulli the First, and maintained a justifiable lifelong admiration and affection for the family.

    These results are essentially Newtonian but were in the cases n = 1, 2, 3, 4 first derived by Albert Girard (1590–1633), of Lorraine (Girard [1629]). (Girard was also the first to write cube and fourth roots as −3√,−4√.) Newton’s derivation was “an unproved generalization of his computations on the coefficients (expressed as symmetric functions of the roots) of an equation of the eighth degree. No rigorous demonstration of the rule was published till the contents of Maclaurin’s letter to Stanhope on July 8, 1743 systematically establishing it was printed by the Publisher’ (Patrick Murdoch?) in Part II, Chapter XII of Maclaurin’s posthumous A Treatise of Algebra ..., pp. 286–296.” Cf.

    This result was first discovered by Euler. Cf., e.g., Nörlund [1924], pp. 23–26. The form of R„ has been discussed by a number of people, including Darboux and Hermite (cf. Nörlund [1924], p. 34.) The first 20 Eulerian numbers are tabulated by Nörlund [1924], p. 458. Boole’s result appears in Boole [1880]. The so-called Boole polynomials are discussed at length by Jordan [1939], pp. 317ff. He also gives another form of a summation formula of Boole. It involves differences instead of derivatives and the Boole instead of the Euler polynomials. These Boole polynomials may be defined with the help of the relationGoogle Scholar

    Attached to Euler 1, XII [1768/69], pp. 415–542, are commentaries written by an Italian humanist and mathematician, Lorenzo Mascheroni (1750–1800), who first taught in a gymnasium in Ticino and then became professor of mathematics in Pavia (cf. Mascheroni [1790] and [1792]). On p. 431 of Euler 1, XII [1768/69], Mascheroni gives Euler’s constant as 0.577215 664901 532860 61811 090082 39 (cf. also p. 442); later Gauss recalculated the constant and in 1878 J. C. Adams (Adams I [1878]) gave its value to 263 places. Mascheroni’s value was wrong in the 20th, 21st, and 22nd places. It is interesting to see how Mascheroni expressed definite integrals. He wrote, e.g., He used this notation throughout whereas Euler wrote, e.g., the integral and then added the words integration ab x = 0 ad x = 1.Google Scholar

    Euler 1, X [1755], p. 384. Thus, e.g., in the expression for 1 − 23 + … the trinomial with the in front is to be discarded, leaving for the infinite sum −1/8. It was not until Gauss investigated the hypergeometric series that we find a true discussion of convergence. Later Cauchy, in his Analyse Algébrique (Paris, 1821) also gave a rigorous treatment of series convergence; it should be noted though that Leibniz did give a criterium for the convergence of alternating series.

    Lagrange I [1762], pp. 493–498. The study of this equation is central to Lagrange’s work on “Fourier” series. It is in his famous method of “variation of parameters,” which he may have evolved from a study of Euler’s method for analyzing the perturbations in the orbits of the moon and planets caused by third bodies. It was used by Euler to study the famous “three-body problem” of astronomy. Cf. Euler 2, I [1736/42]. Lagrange hailed this as the first great application of analysis to dynamics.Google Scholar
