Co-vertices : .
Length of the major axis is .
Since the -coordinates of the co-vertices are same, the ellipse is vertical.
The standard form of vertical ellipse is .
Where ,
,
: length of semi major axis,
: length of semi minor axis,
Center : ,
Foci : ,
Vertices : ,
Co-vertices : ,
Major axis : ,
Minor axis : .
Length of the major axis is equals to .
.
The center is located the mid point of co-vertices.
\So, .
The distance between co-vertices is equals to .
.
Substitute the values ,
and
in standard form of vertical ellipse.
.
The ellipse equation is .
