ellipse standard equation
Answers
An ellipse is the set of all points in a plane such that the sum of the distances from T to two fixed points F1 and F2 is a given constant, K.
In the demonstration above, F1 and F2 are the two blue thumb tacks, and the the fixed distance is the length of the rope.
TF1 + TF2 = K F1 and F2 are both foci(plural of focus) of the ellipse.
The major axis is the segment that contains both foci and has its endpoints on the ellipse. These endpoints are called the vertices. The midpoint of major axis is the center of the ellipse.
The minor axis is perpendicular to the major axis at the center, and the endpoints of the minor axis are called co-vertices.
The vertices are at the intersection of the major axis and the ellipse.
The co-vertices are at the intersection of the minor axis and the ellipse.
You can think of an ellipse as an oval.

Answer:
(x²/a²)-(y²/b²)=1
Step-by-step explanation:
In this equation;
a is the semi major axis
b is the semi minor axis
x and y are points
b is also equal to √(a²-c²)
