The vertices are and minor axis end points are
.
The center is mid point between two vertices : .
Center is .
Length of the semi minor axis is the distance between center and minor axis end point :
\Thus, the length of the semi minor axis is .
The length of the major axis is the distance between center and vertex :
\Thus, the length of the semi major axis is .
The standard form of a ellipse is .
.
The ellipse equation is .
