Extractions: Version for printing Pierre Wantzel Saint-Venant relates in [4] that ... he showed, with his great memory, a marvellous aptitude for mathematics, a subject about which he read with extreme interest. He soon surpassed even his master, who sent for the young Wantzel, at age nine, when he encountered a difficult surveying problem. Bobillier By 1829, at the remarkably young age of 15, he edited a second edition of Reynaud 's Treatise on arithmetic In ... he threw himself into mathematics, philosophy, history, music, and into controversy, exhibiting everywhere equal superiority of mind. Saint-Venant in [4] says that Wantzel:- ... said merrily to his friends that he would be but a mediocre engineer. He preferred the teaching of mathematics... Wantzel is famed for his work on solving equations by radicals . In 1837 Wantzel published proofs of what are some of the most famous mathematical problems of all time in a paper in Liouville 's Journal on ... the means of ascertaining whether a geometric problem can be solved with ruler and compasses Gauss had stated that the problems of duplicating a cube and trisecting an angle could not be solved with ruler and compasses but he gave no proofs. In this 1837 paper Wantzel was the first to prove these results. Improved proofs were later given by Charles

Extractions: , de Descartes et de Gauss Théorème de Wantzel Abel Un nombre constructible est donc est constructible ! Conséquence 1 : la duplication du cube est impossible : Selon le théorème de Wantzel, n'est pas constructible et par suite et la duplication du cube est impossible Q et non constructible. Conséquence 2 : la quadrature du cercle est impossible : quadrature p est transcendant Lindemann p . Il faut donc construire p Quadrature approchée du cercle selon Dinostrate Conséquence 3 : la trisection de l'angle est impossible : trisection de l'angle x : par projection, cos x = OH et la formule : x - 3cos x montre que cos Il est clair que les angles de 180° et 90° sont trisectables ; d'ailleurs si x est trisectable, son double (par report) et sa moitié (bisection) le sont aussi. Ainsi 45° est trisectable : Q p Or, il est facile de prouver ci-dessous Gauss Noter que les mathématiciens arabes avaient déjà soupçonné l'impossibilité de la trisection géométrique de l'angle en ramenant le problème, comme le fit ultérieurement Al-Biruni : N = b /2. Donc b est pair. Posons b = 2c. Il vient a
