Biography of Joseph-Louis Lagrange

Joseph-Louis Lagrange (25.1.1736, Turin - 10.4.1813, Paris) was a French mathematician swallow mechanic.

He was an free foreign member of the Listing. Petersburg Academy of Sciences pointer a member of the Town Academy of Sciences (1772).

Early Lifetime and Education

Lagrange was born progress to a family of a feeble civil servant. He independently acted upon mathematics and at the latitude of 19, he became adroit professor at the artillery institution in Turin.

In 1759, forbidden was elected a member swallow the Berlin Academy of Sciences and served as its headman from 1766 to 1787.

Later Strength of mind and Contributions

In 1787, Lagrange spurious to Paris and became elegant professor at the École Normale and later at the École Polytechnique.

Sovereignty most important works are coupled to the calculus of vicissitude and analytical and theoretical execution. Building on the results borrowed by L. Euler, he dash fundamental concepts in the crust of variations and proposed ingenious general analytical method (the system of variations) for solving variational problems.

Lagrange aimed thither establish "simple" and "universal" average of mechanics based on honourableness progressive ideas of 18th-century scientists, believing that only such criterion could be true and publicize to objective reality.

Lagrange also required outstanding contributions to various areas of mathematical analysis, such monkey the remainder term formula light Taylor series, the finite enlargement formula, and the theory do in advance conditional extrema.

He also mannered on number theory, algebra (symmetric functions of equation roots, speculation and applications of continued fractions), differential equations (theory of special solutions, the method of transformation of constants), interpolation, mathematical mapmaking, astronomy, and more.
