conic section造句怎么写

His chief work was on the conic sections But he also wrote on other subjects.

But don't ask for an explanation of his elegant proof unless you are interested in conic sections.

Closed curve, one of the conic sections of analytic geometry, consisting of all points whose distances from each of two fixed points (foci) add up to the same value.

By using transformation thought, this paper obtains the focus chord of all kinds of conic section through analyzing a sample in conic section teaching.

A fixed point whose relationship with a directrix determines a conic section.

A conic section whose plane is not parallel to the axis base or generatrix of the intersected cone.

After coordinate system were reconstructed,the horizontal and vertical axes of the modeled lens surface were calculated,and the best curve fitting to any conic section was determined.

Some examples are given by inscribed and circumscribed circles of polygons, lines intersecting and tangent to conic sections, the Pappus and Menelaus configurations of points and lines.

The fixed curve traversed by a generatrix in generating a conic section or a cylinder.

Given a hexagon inscribed in a conic section, the three pairs of the continuations of opposite sides meet on a straight line, called the Pascal line.

"Closed curve, one of the conic sections of analytic geometry, consisting of all points whose distances from each of two fixed points (foci) add up to the same value. "

Greek mathematician who first defined the conic sections called the parabola, hyperbola, and ellipse.

This article is to illustrate that the conic section is an envelope of family of straight lines, thus we discover the internal relations between the conic section and the solution of differential equation.
