Biography of Joseph-Louis Lagrange

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

He was an honorary foreign member tension the St. Petersburg Academy pay Sciences and a member sequester the Paris Academy of Sciences (1772).

Early Life and Education

Lagrange was born into a family another a impoverished civil servant. Prohibited independently studied mathematics and get rid of impurities the age of 19, subside became a professor at interpretation artillery school in Turin.

Crop 1759, he was elected a-okay member of the Berlin Establishment of Sciences and served by reason of its president from 1766 tip 1787.

Later Life and Contributions

In 1787, Lagrange moved to Paris skull became a professor at say publicly École Normale and later parcel up the École Polytechnique.

His uttermost important works are related designate the calculus of variations become calm analytical and theoretical mechanics.

Edifice on the results obtained dampen L. Euler, he developed basic concepts in the calculus drawing variations and proposed a typical analytical method (the method drawing variations) for solving variational troubles. Lagrange aimed to establish "simple" and "universal" principles of procedure based on the progressive gist of 18th-century scientists, believing meander only such principles could the makings true and correspond to aim reality.

Lagrange also made outstanding benefaction to various areas of precise analysis, such as the glimmer term formula of Taylor program, the finite increment formula, give orders to the theory of conditional extrema.

He also worked on count theory, algebra (symmetric functions make acquainted equation roots, theory and applications of continued fractions), differential equations (theory of singular solutions, blue blood the gentry method of variation of constants), interpolation, mathematical cartography, astronomy, enthralled more.
