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。
Ellipse - Get an introduction to the topic of an ellipse and learn about the ellipse formula along with some important equations of ellipse like the tangent equation, chord equation and more.
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 ...

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...
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...
