rectrix's Usage Examples:

lateral surface of a cylinder or cone, a conical surface with elliptical directrix, the right conoid, the helicoid, and the tangent developable of a smooth.

Conversely, two tangents which intersect on the directrix are perpendicular.

a directrix is a curve associated with a process generating a geometric object, such as: Directrix (conic section) Directrix (generatrix) Directrix (rational.

The underside of the tail is dark, but each rectrix is broadly tipped with white.

The first one uses an ellipse as directrix, the second one a hyperbola: In the x-y-plane the directrix is the ellipse with equation x 2 a 2 + y.

little or no white edging on the tertials and less white on the fourth rectrix of the tail.

university in Germany is called a president, rector magnificus (men) or rectrix magnifica (women), as in some Belgian universities.

The typical "notched" shape of the second rectrix (R2) is considered an important field mark to distinguish the adult male.

proportional to the distance from a fixed line (the directrix), the constant of proportionality being called the eccentricity.

directrix, are in a fixed ratio, called the eccentricity.

cylinder or cone, a conical surface with elliptical directrix, the right conoid, the helicoid, and the tangent developable of a smooth curve in space.

The parabola is the locus of points in that plane that are equidistant from both the directrix and.

perimeter of the base of a cone is called the "directrix", and each of the line segments between the directrix and apex is a "generatrix" or "generating line".
