Франсуа́ Вие́т, сеньор де ля Биготь

Франсуа́ Вие́т, сеньор де ля Биготье годы жизни с 1540 по 1603 - французский математик, основоположник символической алгебры.
Виет родился в провинции Пуату — Шарант. Он учился в местном монастыре после в университете Пуатье, где получил степень бакалавра. В 1567 пошел на государственную службу. Виет сделал блестящую карьеру и стал советником сначала короля Генриха третьего, а после его убийства — Генриха четвертого. По поручению Генриха четвертого Виет сумел расшифровать переписку испанских агентов во Франции, за что был даже обвинён испанским королём Филиппом вторым в использовании чёрной магии. Когда в результате придворных интриг Виет был на несколько лет отстранён от дел (1584—1588), он полностью посвятил себя математике.
Виет везде делит изложение на две части: общие и конкретные вычисления. Не только неизвестные, но и параметры он обозначал буквами и ввел термин «коэффициенты». Символика Виета была высоко оценена другими учеными, которые стали её совершенствовать. Другие научные заслуги Виета:
1) знаменитая «формула Виета»
2) Новый тригонометрический метод решения неприводимого кубического уравнения
3) Формула для приближения числа пи
4) Полное аналитическое изложение теории уравнений первых четырёх степеней.
И многое другое .

François Viète, Senor de la Bigot years of his life from 1540 to 1603 -. French mathematician, founder of symbolic algebra
Wyeth was born in the province of Poitou - Charentes. He studied at the local monastery after Poitiers University, where he received a bachelor's degree. In 1567 he went to the public service. Wyeth made a brilliant career and became an adviser to King Henry the third, first, and after his assassination - Henry the Fourth. On behalf of Henry the fourth Wyeth was able to decipher the conversation of the Spanish agents in France, for which he was even accused by the Spanish King Philip II in the use of black magic. As a result of court intrigues Wyeth was a few years removed from Minister (1584-1588), he devoted himself entirely to mathematics.
Wyeth everywhere presentation divides into two parts: general and specific calculations. The term "factors" is not only unknown, but he and the parameters designated by letters and entered. Vieta Symbolism was highly praised by other scientists, who have been to improve it. Other scientific merits Vieta:
1) the famous "Wyeth formula"
2) A new method for solving trigonometric irreducible cubic equation
3) The formula for the approximation of pi
4) Full analytical exposition of the theory of equations of the first four degrees.
And much more.
