Complex numbers first appeared in the study of polynomial equations and their solutions. For example, the equation x has the solution x equals the square root of . However, in terms of real numbers, there is no solution for the equation x ; the new number is written as i equals the square root of A man by the name of Rafael Bombelli took the bold step in recognizing imaginary numbers as a necessary vehicle that would transport the mathematician from real cubic equations to its real solutions. Bombelli tried to solve the equation x ; he used a technique that gave him the equation x = (2 + (-121) , and discovered that The original equation included the square root of . Since it is known that the square root of is i , I have chosen to use i. = (2 + i) = (4 + 4i + i ) (2 + i) + i = 8 + 12i -4 -2 - i From this it can be seen that the expression ( is equal to (2 + i) .

Extractions: To do mathematics, that is, in order to understand and to make contributions to this discipline, it is necessary to study its history. Mathematics is constantly building upon past discoveries. Those who wish to study a particular field of mathematics, whether it be statistics, abstract algebra, or continued fractions, will first need to study their field's past. In doing so, one is able to build upon past accomplishments rather than repeating them. The origin of continued fractions is hard to pinpoint. This is due to the fact that we can find examples of these fractions throughout mathematics in the last 2000 years, but its true foundations were not laid until the late 1600's, early 1700's. The origin of continued fractions is traditionally placed at the time of the creation of Euclid's Algorithm.[6] Euclid's Algorithm, however, is used to find the greatest common denominator (gcd) of two numbers. However, by algebraically manipulating the algorithm, one can derive the simple continued fraction of the rational p/q as opposed to the gcd of p and q. (To see this, check out Theorem 1.) It is doubtful whether Euclid or his predecessors actually used this algorithm in such a manner. But due to its close relationship to continued fraction, the creation of Euclid's Algorithm signifies the initial development of continued fractions. For more than a thousand years, any work that used continued fractions was restricted to specific examples. The Indian mathematician Aryabhata (d. 550 AD) used a continued fraction to solve a linear indeterminate equation.[6] Rather than generalizing this method, his use of continued fractions is used solely in specific examples.

Extractions: LE EQUAZIONI DI TERZO GRADO La risoluzione delle equazioni di terzo grado aveva appassionato i matematici di tutti i tempi, poichè era frequente imbattersi in problemi di grado superiore al secondo. Per quanto riguarda la soluzione algebrica delle equazioni cubiche, visti gli insuccessi, gli algebristi concludevano che il caso era impossibile oppure procedevano per tentativi. che gli era stata proposta da un astronomo di Federico II. Fibonacci pervenne al sorprendente valore approssimato x =1,3688081. Nel 1500 cominciarono a circolare voci sui progressi della matematica in campo algebrico, tanto è vero che nel 1530 Zuanne de Tonini da Coi inviò a Tartaglia due problemi che si risolvevano con equazioni di 3° grado. Assai polemica fu la lettera di Tartaglia in risposta a Zuanne, riportata nel Quesito XIII : "… et dico che vi dovreste alquanto arossire, a proponere da rissolvere ad altri, quello che voi medesimo non sapeti rissolvere…". ".. conducevano l’operatore in el capitolo de cosa e cubo equal a numero…"

Extractions: Algebra and Geometry in the Sixteenth and Seventeenth Centuries Home Online Articles Links ... Recommend a Friend Introduction After outlining the state of algebra and geometry at the beginning of the sixteenth century, we move to discuss the advances in these fields between 1500 and 1640. A separate section is devoted to the development and use of algebraic geometry by Descartes, Fermat and Newton. We close with an attempt to assess the relative importance of these developments. State of the Arts: Chuquet and Pacioli At the beginning of the sixteenth century, mathematics was dominated by its Greek heritage and therefore by the study of geometry. But algebra was not wholly absent, and significant advances in notation had been made towards the end of the fifteenth century. Two works were particularly important in this regard: Nicolas Chuquets (c.1440-c.1488) Triparty (1484) and Luca Paciolis (c.1445-1517) Summa (1494). Paciolis symbolism was limited, consisting mostly of abbreviations. Although Chuquets symbolism was more advanced, the influence of this work was limited by its very small circulation: it was not properly published until 1880. Algebraic Advances: Cardano, Bombelli, Viète and Harriot

Extractions: April 2, 1997 Algebra in the Renaissance The general cultural movement of the renaissance in Europe had a profound impact also on the mathematics of the time. Italy was especially impacted. The Italian merchants of the time travelled widely throughout the East, bringing goods back in hopes of making a profit. They needed little by way of mathematics. Only the elementary needs of finance were required. After the crusades, the commercial revolution changed this system. New technologies in ship building and saftey on the seas allows the single merchant to become a shipping magnate. These sedentary merchants could remain at home and hire others to make the journeys. This allowed and required them to make deals, and finance capital, arrange letters of credit, create bills of exchange, and make interest calculations. Double-entry bookkeeping began as a way of tracking the continuous flow of goods and money. The economy of barter was slowly replaced by the economy of money we have today. Needing more mathematics, they inspired the emergence of a new class of mathematician called

Extractions: Raiz quadrada de um número negativo? Cardano não poderia imaginar em 1542 o avanço matemático que sua dúvida produziria, pois seus colegas de ofício argumentaram ser pura ingenuidade questionar ( ). Sufocado pelas críticas e problemas familiares - um de seus filhos foi enforcado -, Cardano abandona a Matemática e passa a dedicar-se à Medicina. Rafael Bombelli, trinta anos depois, volta à dúvida de Cardano e a discute em termos de raízes de equações, para as quais criou uma notação própria. Apesar desse estudo de Bombelli não ter elucidado o conceito de raiz quadrada de um número negativo, influenciaria, e muito, René Descartes, que, em 1637, convocaria os filósofos europeus para desenvolverem tal assunto que chamou de Étude Imaginaire (Estudo Imaginário). Leibniz não concordou com esse nome por achá-lo inexpressivo, e em 1702 propôs
