$\"\"$

\

The co-vertices are $\"\"$ and $\"\"$ .

\

Eccentricity is $\"\"$ .

\

Find value of $\"\"$ .

\

$\"\"$

\

Thus, the value of $\"\"$ is $\"\"$ .

\

The center of the ellipse is midpoint of the co–vertices.

$\"\"$

\

$\"\"$

\

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

\

Eccentricity is $\"\"$ .

\

Substitute $\"\"$ in the above formula.

\

$\"\"$

\

The value of $\"\"$ is $\"\"$ .

\

$\"\"$

\

Find the value of $\"\"$ .

\

$\"\"$

\

Substitute $\"\"$ and $\"\"$ in above equation.

\

$\"\"$

\

$\"\"$

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

Since $\"\"$ –term is same for each co–vertex, ellipse is oriented vertically.

\

Standard form of equation of ellipse is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ and $\"\"$ .

\

$\"\"$

\

Thus, the equation of the ellipse is $\"\"$ .

\
