Jean Frédéric Frenet

from Wikipedia, the free encyclopedia

Jean Frédéric Frenet (born February 7, 1816 in Périgueux , † June 12, 1900 ibid) was a French mathematician , astronomer and meteorologist .

Frenet studied at the University of Toulouse . The Frenet formulas established by him in his doctoral thesis and named after him (they are also called Frenet-Serret formulas after Joseph Serret , who gave them in full) are fundamental for the description of curves in space . As early as 1847, the year of his doctorate, he received a professorship in Toulouse. A year later he moved to the University of Lyon , where he also became director of the local observatory , where he also carried out meteorological measurements. In 1852 he published the Frenetian formulas in the Journal de Mathématiques Pures et Appliquées .

In 1856 his introduction to analysis ( Recueil d'exercices sur le calcul infinitésimal ) was published. It reached seven editions, the last appeared in 1917.
