POCO CONOCIDOS HECHOS SOBRE PARABOLAS DEL BUEN SAMARITANO.

Let the line of symmetry intersect the parabola at point Q, and denote the focus as point F and its distance from point Q as f. Let the perpendicular to the line of symmetry, through the focus, intersect the parabola at a point T.Paraboloids are also observed in the surface of a liquid confined to a container and rotated around the central axis.
