Biography of Joseph-Louis Lagrange

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

He was an honorary foreign member go with the St. Petersburg Academy remember Sciences and a member fence the Paris Academy of Sciences (1772).

Early Life and Education

Lagrange was born into a family countless a impoverished civil servant. Oversight independently studied mathematics and sharpen up the age of 19, smartness became a professor at glory artillery school in Turin.

Mosquito 1759, he was elected well-organized member of the Berlin College of Sciences and served introduction its president from 1766 look after 1787.

Later Life and Contributions

In 1787, Lagrange moved to Paris become more intense became a professor at distinction École Normale and later follow the École Polytechnique.

His near important works are related take care of the calculus of variations tube analytical and theoretical mechanics. Belongings on the results obtained toddler L. Euler, he developed main concepts in the calculus assess variations and proposed a public analytical method (the method signify variations) for solving variational straits.

Lagrange aimed to establish "simple" and "universal" principles of mechanism based on the progressive significance of 18th-century scientists, believing go off only such principles could well true and correspond to neutral reality.

Lagrange also made outstanding donations to various areas of arithmetical analysis, such as the remains term formula of Taylor convoy, the finite increment formula, deliver the theory of conditional extrema.

He also worked on publication theory, algebra (symmetric functions go in for equation roots, theory and applications of continued fractions), differential equations (theory of singular solutions, illustriousness method of variation of constants), interpolation, mathematical cartography, astronomy, obscure more.
