A method similar to Vieta's formula can be found in the work of the 12th century Arabic mathematician Sharaf al-Din al-Tusi. It is plausible that the algebraic advancements made by Arabic mathematicians such as al-Khayyam, al-Tusi, and al-Kashi influenced 16th-century algebraists, with Vieta being the most prominent among them.

Using the formula relating the general cubic and the associated depressed cubic, this implies that the discriminant of the general cubic can be written as (+). It follows that one of these two discriminants is zero if and only if the other is also zero, and, if the coefficients are real , the two discriminants have the same sign.
Viète obtained his formula by comparing the areas of regular polygons with 2 n and 2 n + 1 sides inscribed in a circle. [1] [2] The first term in the product, /, is the ratio of areas of a square and an octagon, the second term is the ratio of areas of an octagon and a hexadecagon, etc.
Formula E is the only other single-seater racing series to have FIA World Championship status outside of Formula 1. There are 11 teams this year and 22 drivers for the season. There are 11 teams ...
Live broadcasts of Formula One Championship races were available on Viasat's pay-TV-channel V Sport + / 1 / 2, which replaced C More Max in 2022. Current main commentator since 2017 is Niki Juusela. Before him Formula One Championship races commentate Matti Kyllönen (1985–2009), Tomi Tuominen (2001–2003) and Oskari Saari (2004–2016).
The derivative of a cubic function is a quadratic function. A cubic function with real coefficients has either one or three real roots (which may not be distinct); [1] all odd-degree polynomials with real coefficients have at least one real root. The graph of a cubic function always has a single inflection point.
Life was a Formula One constructor from Modena, Italy. The company was named for its founder, Ernesto Vita ("Vita" is Italian for "Life"). [1] Life first emerged on the Formula One scene in 1990, trying to market their unconventional W12 3.5-litre engine.
A fast-spreading wildfire that erupted this week about 45 miles northwest of Los Angeles roared from nothing to nearly 10,000 acres − in a matter of hours.
