# Tartaglia formula

## 1949 brooklyn new york

I am not sure how to interpret your formula : IC = 2(% correct) - 1. , care to elaborate? If IC is identical to the correlation coefficient (Corr) then the formula should be cov/std_a*std_b, right? And again, if it is indeed defined between -1 and 1, why are Wiki and Investopedia claiming that it is defined between 0 and 1? Thanks, Tartaglia Based on Tartaglia's formula, Cardan and Ferrari, his assistant, made remarkable progress finding proofs of all cases of the cubic and, even more impressively, solving the quartic equation. Tartaglia made no move to publish his formula, despite the fact that, by now, it had become well known that such a method existed.

Niccolò Fontana Tartaglia (1499/1500, Brescia, Italy – December 13, 1557, Venice, Italy) was a mathematician, an engineer (designing fortifications), a surveyor (of topography, seeking the best means of defense or offense) and a bookkeeper from the then-Republic of Venice (now part of Italy). En Matemáticas hay infinidad de triángulos, y algunos de ellos merecen especial mención. El Triángulo de Tartaglia no es un triángulo en el sentido geométrico de la palabra, sino una colección de números dispuestos en forma triangular que se obtienen de una manera muy sencilla.

About 1535, Nicolo Fontana (1499-1557), better known as Tartaglia (the stammerer), found a formula for solving an equation x^3 + px^2 = q lacking the linear term. Being challenged by Fior, he also came up with a way of solving equations without the quadratic term. En realitat el descobriment de la solució de les equacions cúbiques no es deu ni a Cardano ni a Tartaglia (Scipione del Ferro havia aconseguit una primera fórmula al voltant de 1515) i avui es reconeix l'honradesa de Cardano, que així ho va manifestar. The discovery by Ferro, Tartaglia, and Cardano of an exact algebraic expression for the roots of a cubic equation around 1500 has sometimes been cited as a significant event in the emergence of modern scientific thought, because it was (supposedly) one of the first instances in which European scholars surpassed the knowledge of the ancient Greeks.

I may have misunderstood something there, but that formula only gives me the correct volume if edges are equal. With edges 3,4,4,5,5,sqrt(32) the volume should be 8. Based on Tartaglia's formula, Cardan and Ferrari, his assistant, made remarkable progress finding proofs of all cases of the cubic and, even more impressively, solving the quartic equation. Tartaglia made no move to publish his formula, despite the fact that, by now, it had become well known that such a method existed. 1.1.1.1 el exito de tartaglia en el duelo llega a odios de gerolamo cardano que le ruega que le comunique su formula a lo que accede a cardano jurar que no la publicara sin embargo en vista de que tartaglia no publica su formula y que segun parece llega a manos de cardano un escrito inedito de otro matematico fechado con anterioridad de ...

competencia entre Tartaglia y Fiore, le suplic o a Tartaglia que le diera a conocer la soluci on de la ecuaci on cubica, ofreci endole incluirla en su pr oximo libro Practica Artimeticae (1539), con el nombre de Tartaglia. As equações para a solução de equações cúbicas reduzidas foram descobertas por Niccolò Tartaglia, e segundo Cardano ainda antes por Scipione del Ferro. A contribuição de Cardano foi o método para a redução da equação geral do terceiro grau para o caso especial.

Tartaglia later derived a general formula, with which he defeated Fior in a 1535 contest. Being a poor schoolteacher, he wanted to use his still undivulged knowledge to bargain his way into a higher-paying position. Well-known mathematician Giuseppe Cardano managed to obtain Tartaglia's secret on the condition that he not publish it. John Nicholas Tartaglia (born February 16, 1978) is an American singer, actor, dancer, and puppeteer. His career began at the age of 16 performing as a puppeteer for Sesame Street. He later originated the roles of Princeton (the recent college grad) and Rod (the closeted Republican-investment...
