An ellipse is a geometric shape that is generated when a plane intersects a conical shape and produces a closed curve. Circles are a special subset of the ellipse. Though any particular formula for these shapes may seem rather complex, they are a common form in natural systems such as in o...

In its original physical sense, an ellipse is the figure you can draw in the sand by the following process: Push two sticks vertically down into the sand. Take a piece of string and form a loop that is big enough to go around the two sticks and still have some slack. Take a third ...
C. (x^2)/(a^2)+(y^2)/(b^2)=1. D. y^2 = 4ax. 相关知识点: 试题来源: 解析 C。中文解析:文中提到“The standard equation of an ellipse is (x^2)/(a^2)+(y^2)/(b^2)=1”,即椭圆的标准方程是(x^2)/(a^2)+(y^2)/(b^2)=1。反馈 收藏 ...
An ellipse is ellipse-shaped, of course! Every mathematician knows what an ellipse looks like at least, this is generally true in the Cartesian plane, with the standard distance function or metric. However, there are other metrics which can be applied to the plane 2 and it might be useful...
A circle is rotated 90 degrees. What is it now? A. An ellipse. B. A square. C. Still a circle. D. A rectangle. 相关知识点: 试题来源: 解析 C。本题考查图形旋转后的变化。一个圆旋转 90 度后仍然是一个圆。A 选项椭圆错误;B 选项正方形错误;D 选项长方形错误。
In geometry, an ellipse is a closed curve where the sum of the distances from any point on the curve to two fixed points (the foci) is a constant. The latus rectum is a line segment that passes through one focus of an ellipse and is perpendicular to the ellipse's directrix. In this...
