Avant le symbolisme usage des lettres conclusion Avant l'invention des équations 2000 ans avant JC , on résolvait déjà des équations afin de faire le partage des récoltes entre le Pharaon , les prêtres et les ouvriers . Mais il n'existait aucune méthode générale pour les résoudre ; les équations étaient résolues en faisant une suite de calculs sans justification . Les Indiens employaient des noms de couleurs pour des inconnues. Diophante , mathématicien grec du III e siècle , résout des équations en cherchant un nombre inconnu désigné par un symbole particulier. Mais tout était sous forme de phrases , les notations actuelles n'existaient pas encore . Les mathématiciens arabes du IX e au XIV e siècle ont joué un rôle important dans l'évolution des méthodes de résolution des équations . Cependant , les méthodes de résolution étaient compliquées car ils ne disposaient pas des notations actuelles, et faisaient des phrases . C'est Al-Khwarizmi qui , au IX e siècle , propose une méthode de résolution des équations écrite ci-dessous en notation modernes :

Gerolamo Cardano Born: 1501 Died: 1576 Milan, Italy The story of Cardano comes in the time of the renaissance. Due to the innovation of the printing press ideas are being shared all over europe. This also includes mathematical ideas. One of the most significant results of Cardano's work is the solution to the general cubic equation [2 p 133]. This is an equation of the form: ax + bx + cx + d = which Cardano was able to find solutions for by extracting certain roots [3]. Before we begin with the story of Cardano, we must explain some history associated with the solution of the cubic. Although the solving of equation goes back to the very roots (no pun) of mathematics this segment of the story begins with Luca Pacioli (1445-1509). Paciloi authored a work Summ de Arithmetica , in which he summerized the solving of both linear and quadratic equations. This was a significant work because the algebra of the day was still in a very primitive form. The symbolism of today is not done at this time, but a written description of equations is used. Pacioli ponders the cubic and decides the problem is too difficult for the mathematics of the day [2 p 134]. Scipione del Ferro (1465-1526) continues the work that Pacioli had begun, but is more optimistic. Del Ferro is able to solve the "depressed cubic", that is a cubic equation that has no square term. The depressed cubic that del Ferro works with is of the form x

Section 1.1 The Origin of Complex Numbers Complex analysis can roughly be thought of as that subject which applies the ideas of calculus to the imaginary numbers. But what exactly are imaginary numbers? Usually, students learn about them in high school with introductory remarks from their teachers along the following lines: "We can't take the square root of a negative number. But, let's pretend we can - and since these numbers are really imaginary, it will be convenient notationally to set ." Rules are then learned for doing arithmetic with these numbers. The rules make sense. If , it stands to reason that . On the other hand, it is not uncommon for students to wonder all along whether they are really doing magic rather than mathematics. If you ever felt that way, congratulate yourself! You're in the company of some of the great mathematicians from the sixteenth through the nineteenth centuries. They too were perplexed with the notion of roots of negative numbers. The purpose of this section is to highlight some of the episodes in what turns out to be va very colorful history of how imaginary numbers were introduced, investigated, avoided, mocked, and eventually accepted by the mathematical community. We intend to show you that, contrary to popular belief, there is really nothing imaginary about "imaginary numbers" at all. In a metaphysical sense, they are just as real as are "real numbers." In 1545 the Italian mathematician Girolamo Cardano published "Ars Magna" (The Great Art), a 40 chapter masterpiece in which he gave for the first time an algebraic solution to the

49. A Look To The Past niccolo fontana (tartaglia) (15001557) claimed to be able to solve cubic equationsof the form x3+ mx2 = n. However, he apparently did not know how to solve http://ued.uniandes.edu.co/servidor/em/recinf/tg18/Vizmanos/Vizmanos-2.html

Will elementary algebra disappear with the use of new graphing calculators?. A look to the past What do we understand elementary algebra to be? Elementary algebra is the language with which we communicate the majority of mathematics. Thanks to algebra we can work with concepts at an abstract level and then apply them. Elementary algebra begins as a generalization of arithmetic and then focuses on its own structure and greater logical coherence. From there comes the importance of the various uses of algebraic symbols. When we write A + B, we can be indicating the sum of two natural numbers, the sum of two algebraic expressions, or even the sum of two matrices. Thus there is, at first, representations and symbolism, and later the development of algorithms and procedures to work formally with algebraic expressions. But what we today understand to be algebra has been the fruit of the efforts of many generations that have been contributing their grains of sand in constructing this magnificent building. It seems that the Egyptians already knew methods for solving first degree equations. In the

Vynimocne studovali specialne typy rovnic tretieho alebo stvrteho stupna. Az v 16. storoci sa v tomto smere dosiahol uspech. Geronimo Cardano (1501~ 1576) vo svojom diele Ars magna (Velke umenie, 1545) vyklada metodu riesenia rovnic tretieho a stvrteho stupna. Uvedieme najprv volny preklad jedneho odstavca z toho diela: "Scipione del Ferro z Bologni asi pred tridsiatimi rokmi objavil metodu* vylozenu v tejto kapitole a povedal ju Antoniovi Fiorovi z Benatok, ktory potom, ako sa raz pretekal s Niccolom Tartagliom z Brescii, zistil, ze Niccolo tiez objavil tuto metodu. Niccolo na nasu ziadost tuto metodu povedal nam, no neprezradil dokaz. Vyuzijuc toto, hladali sme dokaz a nasli ho, aj ked s vetkou namahou, a to ten, ktory vysvetlime dalej". To, o com sa tu nepise, ale je zname, je ta skutocnost, ze Cardano slubil Tartagliovi nevyzradit metodu riesenia kubickej rovnice a Tartaglia po publikovani Ars magna obvinil Cardana z porusenia tohto slubu.

This means DO NOT USE THEM OR PRESSURIZE THEM AT ALL. These pipes can tolerate no pressures and will explode if pressurized, causing great harm or death. A friend of a guy named John Rich made the designs of the spud gun. Bob Simon put up a website called " Backyard Ballistics " in 1995 in the city of Houston, Texas. He probably did this for the purposes of fun. This is just the sort of thing that you should expect from a Texan! Note: I am about to tell you how to make one of these things.

DECEMBER 13 - BIRTHS Philip W. Anderson (source) Born 13 Dec 1923 Philip Warren Anderson is an American physicist who (with John H. Van Vleck and Sir Nevill F. Mott) received the 1977 Nobel Prize for Physics for his research on semiconductors, superconductivity, and magnetism. He made contributions to the study of solid-state physics, and research on molecular interactions has been facilitated by his work on the spectroscopy of gases. He conceived a model (known as the Anderson model) to describe what happens when an impurity atom is present in a metal. He also investigated magnetism and superconductivity, and his work is of fundamental importance for modern solid-state electronics, making possible the development of inexpensive electronic switching and memory devices in computers. John Henry Patterson (source) Born 13 Dec 1844; died 7 May 1922. American manufacturer who founded NCR (National Cash Register Co.) and helped popularize the modern cash register by means of aggressive and innovative sales techniques. In the 1870s, when he and his brother Frank established a successful business selling coal and miner's supplies, unrecorded sales were a problem. After reading a description of the cash register designed by James Ritty and sold by the National Manufacturing Company in Dayton, John ordered two, sight unseen. In six months they reduced his debt from $16,000 to $3,000 and the books showed a profit of $5,000. These modern machines had solved the old problems of disorganization and dishonesty. Patterson "was so impressed that he bought the company."

59. History - Page One 1535 niccolo fontana (tartaglia) (1500?1557) wins a mathematical contestby solving many different cubics, and gives his method to Cardan. http://www.vimagic.de/hope/1/

ca. 2000 BC Babylonians solve quadratics in radicals. ca. 300 BC Euclid demonstrates a geometrical construction for solving a quadratic. ca. 1000 Arab mathematicians reduce: ux + vx p = w to a quadratic. Omar Khayyam (1050-1123) solves cubics geometrically by intersecting parabolas and circles. ca. 1400 Al-Kashi solves special cubic equations by iteration. Nicholas Chuqet (1445?-1500?) invents a method for solving polynomials iteratively. Scipione del Ferro (1465-1526) solves the cubic: x + mx = n but does not publish his solution. Niccolo Fontana ( Tartaglia ) (1500?-1557) wins a mathematical contest by solving many different cubics, and gives his method to Cardan. Girolamo Cardan (1501-1576) gives the complete solution of cubics in his book, The Great Art, or the Rules of Algebra . Complex numbers had been rejected for quadratics as absurd, but now they are needed in Cardan's formula to express real solutions. The Great Art also includes the solution of the quartic equation by Ludovico Ferrari (1522-1565), but it is played down because it was believed to be absurd to take a quantity to the fourth power, given that there are only three dimensions.
