Bobillier, Étienne

For a more sophisticated point of view of the same field, his following proposition may be cited: Bobillier is best known, however, for his studies of successive polars of curves or algebraic surfaces, and for his abridged notation.

In this respect he was a disciple of Gergonne.

American Society of Mechanical Engineers Paper. We are testing a new system for linking publications to authors. Annales18pp. Kohli D, Sandor GN. He first set up a problem in the form of an equation in a particular case, simple enough so that the analytic geometry of his time could deal with it.

Tree Info PubMed Report error. Bobillier then went on to pose the problem of how to determine the corresponding center of curvature in the path of the third vertex, gobillierwhen given the centers of curvature at points a and b of the paths described by vertices a and b of triangle abc. Imam I, Sandor GN.

By he was full professor, a rank he retained until his death. After the July Revolutioncivil war broke out again in the west and Bobillier, a volunteer in the National Guard of Angers, fought in a rather hard month-long campaign against the Chouans.

He then presented himself for the competitive entrance examination in If the point describes a straight line, the m—1 2 points at the base of this pencil describe a curve of order 2 m—1. AbstractBobillier’s construction of the center of curvature is derived obbillier a simple geometric reasoning based upon the three-pole theorem.
