Аbstract

There are various ways to specify the quadric using geometric elements in a different position relative to the surface. Attempts to determine the quadric in her nine points for today failed. The report discusses the issue and offers a solution for the definition of quadric in the case where five of the nine points lie in the same plane.

Keywords: involution; the double points; conic; quadric; the job by nine points.
