A brief introduction to the mathematician Veda, who is the mathematician Veda

His deeds include the introduction of systematic algebraic notation and the improvement of equation theory. It also solves the problem of numerical solutions to algebraic equations. In 1593, Veda explained in his Five Analyses how to use a straightedge and compass to make solutions to geometric problems that lead to certain quadratic equations.

In the same year his Supplementum Geometriae was published in Tours, which included some knowledge of algebraic equations involved in the problem of drawing rulers. In addition, Veda was the first to explicitly give an infinite equation for the value of pi and created a set of decimal fraction notation, which promoted the reform of notation. Veda also wrote a special article"Amputation"The general formulas of sine, cosine, and tangent are preliminarily discussed, and algebraic transformations are applied to trigonometry for the first time.

He considers the equation containing the doubling angle, and gives the function of expressing cos(nx) as cos(x) and gives the expression of the doubling angle when n 11 is equal to any positive integer. Because of his many important contributions, Veda became the most prominent French mathematician of the sixteenth century.

A great mathematician.

Weida, a scholar of Shuchang bending bridge, is a native of France. Veda is revered in Europe as the "father of algebra". Veda's most important contribution was the advancement of algebra, and he was the first to systematically introduce algebraic notation to advance the development of equation theory.

Veda uses the word "analysis" to summarize the content and methods of the current era.

He created a large number of algebraic symbols, replaced unknown numbers with letters, and systematically elaborated and improved them.

The solution of the third and fourth order equations points out the relationship between the root and the coefficient. The trigonometric solution of the irreducible case of cubic equations is given. He has compiled and published many works such as "Introduction to Analytical Methods" and "On the Identification and Revision of Equations".

Veda pursued mathematics as a hobby, but he completed great works on algebra and trigonometry. His Mathematical Laws Applied to Triangles is one of Veda's earliest mathematical treatises, and may be the first systematic work in Western Europe to deal with six methods of solving plane and spherical triangles by trigonometric functions. He is known as the father of modern algebraic notation.

Veda also wrote a special article "Angle Interception", which preliminarily discussed the general formulas of sine (sin), cosine (cos), and tangent strings, and applied algebraic transformations to trigonometry for the first time. Considering the equation containing the doubling angle, he gave a function that expresses cos(nx) as cos(x) and an expression of the doubling angle when n 11 is equal to an arbitrary positive integer.

His book "Introduction to Analytical Methods" concentrates his previous achievements in algebra and makes algebra truly an excellent branch of mathematics. His contribution to equation theory was the proposal for the solution of bisecondary, cubic and quadratic equations in the book On the Arrangement and Correction of Equations.

Veda was born in 1540 in Wetnay, Poitou, in eastern France. He studied law in his early years and worked as a lawyer in the French parliament, Veda was not a full-time mathematician, but he enjoyed studying mathematics in between his political career and in his spare time, and made many important contributions, becoming the greatest mathematician of his time.

Veda was the first to consciously and systematically use letters to represent numbers, and many improvements were made to mathematical notation. His Introduction to Analysis, written in 1591, was the earliest work on symbolic algebra. It was he who established the principles and methods of symbolic algebra, systematized algebra at that time, and used algebra as an analytical method.

As a result, he earned the title of "Father of Algebra". He also wrote a number of mathematical treatises, such as the Mathematical Code (1579) and the Mathematical Laws Applied to Triangles (1579). Veda's writings contain all the mathematics of the Renaissance in a unique form.

It is a pity that the text of Veda's work was relatively obscure and could not be widely disseminated at the time. After his death, it was compiled and published in 1646 as the Vedic Anthology. Veda died in Paris in 1603 at the age of 63.

Here are two fun facts about Veda:

Fight with Rohm

The Belgian mathematician Rohm once proposed a problem of 45 equations to challenge mathematicians from all over the world. The king of France gave the problem to Veda, who came up with a solution at the time, and when he returned home, he quickly came up with another 22 solutions. The answer was announced, which shocked the mathematical community.

Veda replied to Rohmon with another question. It took him days of hard thinking and meditation to solve it, but Veda did it easily, and won honor for his country, which is evident in his mathematical attainments.

Veda's "magic".

In the war between France and Spain, the French were always well aware of Spain's military dynamics and could always strike first militarily, so they defeated Spain in less than two years. The poor king of Spain was very confused and incomprehensible to the "unpredictable prophets" of the French in the war, believing that the French had used "magic". It turned out that it was Veda who used his exquisite mathematical methods to successfully decipher the Spanish military code and win the initiative in the war for his homeland.

In addition, Veda designed and improved the calendar. All of this reflects Veda's profound skills as a great mathematician.
