conics

conics的音标是[kənɪksɪs]，基本翻译是圆锥曲线。记忆技巧：conic在英文中表示圆锥形状的，而sc表示曲线，所以conic可以用来表示圆锥曲线。

Conics这个词来源于希腊语，意为“圆形的”。它的变化形式包括名词形式conic（圆的）、形容词形式conical（圆形的）、副词形式conically（圆地）等。

相关单词：

1. Eccentricity（偏心距）：这是一个名词，用来描述圆周上一点到圆心的距离与到其焦点距离之间的关系。这个词也经常用来形容人的性格或行为具有某种偏离常规的特点。

2. Conic section（圆锥曲线）：这是一个名词，指的是在平面内，一个动点与一个定点和一条定直线之间的距离始终相等，这样的轨迹形成的图形就是圆锥曲线。

3. Conic cone（圆锥）：这是一个名词，指的是由一个圆锥面围成的空间，通常用于存储或建造小型结构。

例如，conic cone可以解释为“由圆锥面构成的圆锥”，而其变化形式conical也可以用来描述“具有锥形特征的”或者“近似圆锥的”。在英语中，conic section还可以用来描述“圆锥曲线”这一数学概念，而eccentricity则可以用来形容人的性格或行为具有某种偏离常规的特点。这些单词都与conics这个词有着密切的联系，并且可以用来描述各种与圆和圆锥相关的概念和现象。

Conics:常用短语

1. on the ellipsoid of revolution of the cone over the axis

2. on the hyperboloid of one sheet of the cone over the axis

3. on the surface of the cone

4. in the plane of the base cone

5. at infinity

6. on the axis

7. at a distance from the axis

双语例句：

1. The particles are moving on the surface of the cone, not on the ellipsoid of revolution of the cone over the axis.

2. The light rays are hitting the conical object at infinity.

3. The base cone is at a distance from the origin, so the conic section is not on the axis.

4. The conical object is at a distance from the observer, so it is not in the plane of the base cone.

5. The conical section is formed by rotating a cone around its axis and cutting it at a certain distance from the axis.

6. The conical section is a mathematical model of a cone that is cut by a plane perpendicular to its axis and intersects it at a point.

7. The conic section is an important tool in geometry and physics, used to describe the shape of objects that are not perfectly circular or rectangular.

Title: Conic Sections - Shape of Nature

Conic sections are mathematical models that describe the shape of objects that are not perfectly circular or rectangular. From a simple cone to more complex hyperbolas, these curves help us understand how nature shapes its forms in a variety of ways.

From mountains to galaxies, conic sections provide us with a way to visualize and analyze shapes that are not easily represented by simple geometric figures. From the slanting rays of sunlight hitting a conical object to the curved trajectories of celestial bodies, conic sections help us understand how nature uses different shapes to create beautiful and interesting patterns.

In nature, we see ellipses formed by winds, hyperbolas created by waves, and cones everywhere from trees to human bodies. Conic sections not only help us understand these shapes, but also inspire us to create new ones and find new uses for them in engineering, art, and science. Through conic sections, we can see how nature uses simplicity and diversity to create beautiful and interesting forms that we can appreciate and learn from.
