In the standard equation of an ellipse, a represents the distance of the major axis, b represents the distance of the minor axis, and c represents the focal length. The ellipse of the ellipse is the locus of the moving point P whose constant is greater than F 1 F2, and the sum of the distances from the fixed points f1and f2 on the plane. F 1 and F2 are called the two focal points of an ellipse, which is a kind of conic curve, that is, the tangent of a cone to a plane.

Characteristics of elliptic standard equation

The circumference of an ellipse is equal to the length of a specific sine curve in a period. Ellipse has two standard equations, depending on the coordinate axis where the focus is located. The standard equation of an ellipse is the sum of squares of two fractions on the left, and 1 on the right. In the standard equation of an ellipse, which denominator of x2 and y2 is larger, and on which axis is the focus?

In the standard equation of ellipse, three parameters abc satisfy that a2 equals b2 plus c2, and the values of three parameters abc can be obtained from the standard equation of ellipse. Mathematically, an ellipse is a curve around two focal points on a plane, which makes the sum of the distances from each point on the curve to the two focal points constant, so it is a generalization of a circle and a special type of ellipse with two focal points at the same position.
