Published in two volumes in , the Introductio takes up polynomials and infinite series Euler regarded the two as virtually synonymous , exponential and logarithmic functions, trigonometry, the zeta function and formulas involving primes, partitions, and continued fractions. This article considers part of Book I and a small part. The Introductio has been massively influential from the day it was published and established the term "analysis" in its modern usage in mathematics. Both volumes have been translated into English by John D.

E -- Introductio in analysin infinitorum, volume 1 Introduction to the Analysis of the Infinite, volume 1 Summary: In E, together with E , Euler lays the foundations of modern mathematical analysis. Perhaps more importantly, the Introductio makes the function the central concept of analysis; in particular, Euler introduces the f x notation for a function and uses it for implicit as well as explicit functions, and for both continuous and discontinuous functions.

Euler also proves that every rational number can be written as a finite continued fraction and that the continued fraction of an irrational number is infinite. The main body of the work is divided into 18 chapters: De functionibus in genere. De transformatione functionum per substitutionem. De explicatione functionum per series infinitas. De functionibus duarum pluriumve variabilium. De quantitatibus exponentialibus ac logarithmis. De quantitatum exponentialium ac logarithmorum per series explicatione.

De quantitatibus transcendentibus ex circulo ortis. De investigatione factorum trinomialium. De usu factorum inventorum in definiendis summis serierum infinitarum. De aliis arcuum atque sinuum expressionibus infinitis. De reali functionum fractarum evolutione. De seriebus recurrentibus. De multiplicatione ac divisione angulorum.

De seriebus ex evolutione factorum ortis. De partitione numerorum. De usu serierum recurrentium in radicibus aequationum indagandis.

De fractionibus continuis. Originally published as a book in Opera Omnia: Series 1, Volume 8. John Blanton has translated both E and E in full. German Translation by H. Maser , available on the Euler Archive:.


Introductio in analysin infinitorum

Ian Bruce Introduction. John D. I hope that some people will come with me on this great journey : along the way, if you are unhappy with something which you think I have got wrong, please let me know and I will fix the problem a. There are of course, things that we now consider Euler got wrong, such as his rather casual use of infinite quantities to prove an argument; these are put in place here as Euler left them, perhaps with a note of the difficulty.

Written in Latin and published in , the Introductio contains 18 chapters in the first part and 22 chapters in the second. It is doubtful that any other essentially didactic work includes as large a portion of original material that survives in the college courses today Can be read with comparative ease by the modern student The prototype of modern textbooks. The first translation into English was that by John D. Blanton, published in
