\

The focus of the ellipse is $\"\"$ .

\

The vertices of the ellipse are $\"\"$ , $\"\"$ .

\

Since the $\"\"$ -coordinate of vertices and focus are same, the ellipse is vertical.

\

The standard form of ellipse is $\"\"$ .

\

where $\"\"$ is the center of the ellipse, $\"\"$ is the length of the semi major axis and $\"\"$ is the length of the semi minor axis.

\

The center is a mid point of two vertices.

\

The distance between center and vertex is $\"\"$ .

\

The distance between center and focus is $\"\"$ .

\

$\"\"$

\

The mid point of vertices is center of the ellipse.
